Definitions
- biochemical reactions in particular enzymatic reactions
- can be controlled at least partly by temperature since many biological macromolecules, in particular enzymes, have distinct pronounced maxima of their functionality and efficiency at certain temperatures.
- this control is usually limited to a relatively narrow temperature range and larger temperature changes up or down usually lead to the termination of the reaction. Only a few biomolecules are functional even at significantly different operating temperatures, so that cyclic bioreactions at least outside an organism are difficult to control via temperature.
- PCR polymerase chain reaction
- the denatured double strands are denatured again by increasing the temperature in single strands, which can then be cooled after cooling bind new primers and the process repeats itself. If two such primers are inserted in each PCR batch, one of the ones on the sense strand and the second one which binds to the antisense strand, a doubling (chain reaction) of the DNA present between the primers is obtained with each cycle of new synthesis and denaturation. section. If you use a temperature-stable polymerase, as it can be obtained from organisms from hot springs, the reaction proceeds without interruption, if you run temperature cycles. As a rule, one begins between 92-98 0 C with the Denatur réelle of the DNA.
- PCR has become indispensable as a central bioanalytical method in biotechnology and medicine.
- light cyclers and other devices that implement alternative principles for rapid temperature jumps makes the PCR technique robust and fast.
- the high temperatures and also the temperature changes are significant limitations. So far, no other bioreactions have been implemented on a similar principle, since not many macromolecules have the broad temperature stability and reversibility to temperature jumps.
- thermocycling analog control principles for biochemical reactions derived from the success of the temperature-controlled PCR process, the desire and the demand for further, in particular for thermocycling analog control principles for biochemical reactions derived. Since all components in the PCR-analogous process undergo the T cycles, they must at least tolerate the highest temperature without damage and may only be chemically active at their cycle temperature. This limits the macromolecular candidate list strong one, because most of the high temperatures are not tolerated (> 7O 0 C) from normal temperature species taken macromolecules. So far, apart from the temperature-controlled reaction cycles, there are only traditional principles, such as the pH control or the change in the ionic strength of the solution. However, such parameters are not possible without considerable technical measurement effort and above all not without changing the solution composition and volumes. Both are serious disadvantages.
- biocomponents for example macromolecules, such as enzymes, proteins and / or sugars, organelles, such as ribosomes or mitochondrial components, are required which have as little as possible a single technically simple and non-contaminating or altering physical quantity at the operating point Reactants, as they should be called more generally in the following, can be clearly shifted.
- These processes must be Hezu completely, at least long-term reversible.
- the spectrum of usable molecules and components should be significantly wider than that of the PCR technique.
- the modification of this or this parameter should not damage the molecules but only significantly shift their chemical activity (working points). Especially welcome would be a threshold behavior (on / off).
- the present invention is based on the recognition that the above-mentioned physical quantity can also be the pressure and that a control of biochemical reactions can be realized by means of pressure.
- the membrane composition and its transport properties and stability also proved to be highly pressure-dependent (see Pressure-regulated metabolism in microorganisms, Fumiyoshi Abe, Chiaki Kato and Koki Horikoshi, TRENDS IN MICROBIOLOGY 447, Volume 7, No. 11, November 1999).
- 3T3 mouse fibroblasts die at 70 MPa (equivalent to a depth of 7000 m) in culture.
- reaction rate of any chemical reaction that occurs faster or slower as pressure or pressure increases, as system volume increases or decreases, as the relevant thermodynamic quantity.
- Pressure-dependent changes in the thermodynamic system volume should not be confused with volume changes of the organism or a cell. Rather, it is, for example, changes in the attachment of water to macromolecules, ions and membranes.

- Suitable organisms include both macroorganisms (animals, plants, generally multicellular) and microorganisms (especially archaebacteria, bacteria and yeasts). As a rule, microorganisms will be preferred because they are particularly robust and tolerate extreme conditions and are easier to grow and cultivate alive.
- Roundworm nematode

- the pressure-controllable system is a system for storing and processing information, a transport system, a system for generating, Storage or conversion of energy, a membrane system, a sensor, or a switch.
- this system which includes a combination of high pressure optimized and low pressure optimized biocomponents, includes a plurality of adjustable pressure states, wherein the different pressure states each determine a further parameter of the system.
- this additional system parameter may include or represent a particular charge or conformation, a particular information or energy state, etc. of system components.
- Yet another aspect of the present invention relates to a device for carrying out the pressure-controlled method according to the invention, in particular a pressure-controlled biosynthesis method according to the invention.
- Such a general device comprises at least one synthesis chamber (1), a pressure generating system (2), at least one inflow (3), and at least one outflow (4).
- the device will typically still include sensors (5), and means (6) for detecting and processing the data received from the sensors.
- the synthesis chamber comprises two adjustable walls (11,13), the distance of which is adjustable with a spacing system (12), the pressure generating system (2) two adjusting elements (24, 25) connected to a voltage generator (211) and a sturdy frame (212) as an abutment.
- the adjusting elements are piezoelements.
- at least one wall of the synthesis chamber is transparent, eg a pressure-resistant glass plate, for example to allow easy observation of the synthesis reaction.
- the adjustable walls form the lower and upper boundaries of the synthesis chamber and the maximum distance of the adjustable walls is less than the length and width of the adjustable walls.
- FIG. 7 shows an example of such a synthesis chamber with the basic elements for pressure detection and control.
- the actual chamber consists of two plates (71, 73), which can also be thick glass plates, so that the reaction may be observed or light can be radiated. These plates are kept at a distance via a spacer system (72).
- the pressure generation in the more shallow than high synthesis chamber (76) via two piezoverstellelemente (74, 75), which are connected to a voltage generator (711). When energized, they compress the plates (71, 73) of the synthesis chamber, creating the required high pressure in the closed system. In a stable frame (712) these elements find their counter bearing.
- the reaction chamber there may still be sensors (79, pressure, temperature, reactant concentrations, etc.) which are read out via an electronic system (710) and the data are processed. This can be done not only for the purpose of monitoring but also for rule reasons. In particular, the change in pressure in this way becomes programmable and adaptable to the state of the reaction.
- the synthesis chamber has inflows (77a and b) and outflows (78), with two inflows (for example for mixing the HP and NP Reactants) and an outflow are shown.
- the inflows and outflows can be opened and closed with high-pressure valves (713).
- Fig. 8 shows schematically the pressure control in a synthesis device according to the invention (reaction chamber with pressure periphery).
- a reaction chamber (1) is connected via a line system (2) with components for pressure generation and measurement. Individual areas are separated by valves (3).
- the base pressure p ° is introduced from the outside and measured on a first manometer (4).
- a hydraulic amplifier (5) multiplies this pressure by a fixed amplification factor A. This pressure is introduced into the reaction chamber.
- a time-variable pressure p 1 can be superimposed additively with a motorized pump (6).

Between the inner reaction volume (11) and the outer volume (12) can then additionally diffusion window (13) are provided become. Via these, reactants and products can be supplied or removed via a further shut-off valve (3).
- Such devices are suitable both for microsystems (such as typically used for PCR reactions) and for large reaction volumes in the range of milliliters to cubic meters, since pressure is an intrinsic parameter that sets very rapidly throughout the volume (as distinct from temperature, ion concentration or pH). This is an additional advantage over conventional methods.

- An HP reactant will remain an HP reactant, even if it undergoes a reaction and is changed.
- An NP reactant has a very low reaction rate at HP.
- An NP reactant has its maximum reaction rate at NP.
- An HP reactant has a very low reaction rate in NP.
- An HP reactant has its maximum reaction rate at HP.
- An NP reactant has a reduced reaction rate at MP (pressure between HP and NP), but it still reacts.
- An HP reactant has a reduced reaction rate in MP, but it still reacts.
- Biocomponents which as reactants meet the above basic requirements, can be obtained from high pressure or low pressure adapted organisms, tested in routine procedures and then used.
- HP high pressure between 50 and 200 MP, 500 to 2000 atm
- MP - intermediate pressure between 10 and 50 MPa, 100 to 500 atm
- NP - low pressure between 0.1 and 10 MPa, 1 to 100 atm
- a cell lysate from a deep-sea organism in which then many or all components are HP-optimized.
- This can also be an in vitro cell culture produced from such an organism or by adaptation, which is cultured under high pressure and delivers the cytoplasmic lysate.
- the DNA-related reaction processes are very strongly pressure-dependent. This means that in an organism from 6000 - 10000 m depth, the optimal working range of the macromolecular components at a pressure of 60 to 100 MPa (600 to 1000 atm). For many of these reaction components, their reactivity at atmospheric pressure is reduced to a few percent or less or completely impossible.
- a reactive multicomponent system or else a cell organelle system can be switched on and off via a simple pressure change between, for example, 80 MPa and 0.1 MPa (FIG. 2A). If no such large pressure change is made, the reactions can also be manipulated gradually. This would be the case, for example, if you work in the MP range.
- it is still possible to control the temperature. Deep-sea organisms are usually adapted to very constant temperatures at about 4 0 C. Since changes are in the degree range or less, they are less temperature tolerant than comparative molecules, organelles, etc. isolated from surface organisms.
- the temperature (lower or higher) can be used in this case in addition to connecting or disconnecting the reactions.
- HP cell lysate its reactivity, in addition to the principles already used, can be almost completely controlled by the pressure change.
- NP the system is locked in response and starts to work when the pressure is increased in steps or slowly (HP mode). In this way, cell lysates can be prevented from unwanted or early reaction.
- FIG. 2C Further embodiments represent various admixtures of HP components isolated from deep-sea organisms to cell lysates from NP organisms. These may be, for example, isolated components which are required for the energy supply in the cell lysate (eg ATP / ADP, NADPH / NADH, but also organelles such as mitochondria or living cells, here designated A 1 ) or energy transport (Figure 2B). Furthermore, mixtures of complete cell lysates from HP and NP organisms in a variety of percentages are applicable. In such mixtures, different reaction rates could be set, so that, for example, the accumulation of one or more intermediates is possible (Fig. 2C).
- isolated components which are required for the energy supply in the cell lysate eg ATP / ADP, NADPH / NADH, but also organelles such as mitochondria or living cells, here designated A 1
- Figure 2B energy transport
- mixtures of complete cell lysates from HP and NP organisms in a variety of percentages are applicable. In such mixture
- a further embodiment represents the isolation of certain HP components from an HP cell lysate and the removal or at least depletion of these components in the NP lysate. In this way one or more reactions can be stopped and started by pressure changes (FIG. , Finally, replacement of one or more components in both HP cell lysate and NP cell lysate can be accomplished. In this case, a variety of cyclic reactions can be performed.
- HP and NP components can be isolated from the respective cell lysates and mixed with other basic media, which may be cell lysates or even artificial compositions (FIG. 2 E). In this way mixtures can be put together arbitrarily, in which the reactants freely after the Preselection HP- or NP- are active, which allows various switchable operations in bioreactors.
- Another more specific embodiment are PCR-like systems in pressure-controlled form. Between the individual stages, annealing, polymerase reaction and single-strand production, no temperature changes are made, but only the pressure is changed as described above.
- a variant is shown schematically in FIG.
- the entire duplication cycle can be cycled over periodic pressure changes. This requires that one eliminates the melting of the double strands by heating, which is possible by inserting the helicase. To cycle through the cycle, it cycles from NP to HP and back. Since pressure changes are technically very easily controllable and can be done quickly, it is also possible to work with very small quantities or, secondly, in large volumes. Especially large volumes are problematic for thermocycling.
- FIG. 6 formally shows an example of a regenerable biobattery based on such components.
- the system consists of three compartments (I, II, III) separated by a membrane (dotted vertical lines).
- the membranes contain pressure-sensitive transporters (T) which can carry one component (A) from compartment I to II and back and one component (B) from compartment I to III and back.
- T pressure-sensitive transporters
- component (A) or (B) is transferred to a charged state or otherwise excited so that they can give off energy.
- This compartment is occasionally refilled with reactant mixtures (chemical charging of the battery). Only at HP, the high-energy or charged reactants are transported from I to II or III through the membrane. Only at NP, they can be transported back in the lower-energy form (A, B). The energy is extracted in compartments II and III via a reaction (K) which shows an NP characteristic.
- contamination and decontamination can be reduced or eliminated by pressure changes and by stopping the reaction chains and restarting.
- Another application example is pressure-dependent light-driven processes.
