Definitions
- the invention relates to the production of analytically useful dimethylamine or trimethylamine dehydrogenase (DMA or TMA dehydrogenase) and it encompasses the enzymes obtained thereafter and their use.
- DMA or TMA dehydrogenase analytically useful dimethylamine or trimethylamine dehydrogenase
- Trimethylaminuria is a disorder of the choline metabolism.
- the defective enzyme is trimethylamine N-oxidase, which catalyzes the formation of trimethylamine N-oxide.
- a specific trimethylamine detection is required for the diagnosis.
- mass spectrometry King GS et al. Biomed. Mass Spectrom.
- Paracoccus strains isolated from soil samples can be used to obtain two dehydrogenases that are similar per se and which either - grown on DMA-containing medium - for selective DMA conversion or - grown on TMA-containing medium - are capable of selective TMA implementation.
- the medium was inoculated with 300 ml of a 24-hour-old preculture after the brood temperature had reached 30 ° C.
- the course of the enzyme activity over time could be determined by taking samples at different times and the activity of the TMA dehydrogenase after cell disruption in the cell-free Supernatant was determined.
- FIG. 1 shows that maximum enzyme activity can only be obtained within a short period of time towards the end of the growth phase.
- the 8 1 fermenter was after 21 hours at an OD 660 of 4 - 35 cropped by a centrifuge, to obtain 160 g of wet biomass.
- the biomass can be stored frozen at -20 ° C, whereby no loss of activity can be seen over several months.
- the solution was again applied in 2 ml portions to the Mono-Q column and eluted with a NaCl gradient (0-1 M); the enzyme was detached at a NaCl concentration of 400 mM.
- a specific activity of 4 U / mg was measured in fractions with high enzyme activity.
- An SDS gel prepared with these fractions showed on the basis of the protein staining that the TMA dehydrogenase was here at least 90% purified.
- the enzyme can be released from the cells as in Example 2B.
- the cells are suspended in 0.1 M Tris-HCl buffer (pH 7.0) with the addition of a protease inhibitor (Pefabloc; Pentapharm, Basel, Switzerland) and disrupted by wet grinding with glass beads. After centrifugation (15 minutes at 16000 rpm), the supernatant was filtered (0.45 ⁇ m pores) and then subjected to a further chromatographic separation.
- C Purification using ion exchange chromatography
- the supernatant was subjected to ion exchange chromatography on a Q-Sepharose (Pharmacia, Freiburg FRG).
- the column was equilibrated with 50 mM Na 4 P 2 0 7 buffer pH 9.
- elution was carried out first with two bed volumes of the same buffer, to which 200 mM NaCl had been added, and then with a linear gradient from 200 to 500 mM NaCl (dissolved in the above sodium phosphate buffer).
- the active fractions are combined and concentrated with an ultrafiltration membrane (cut-off 30 kDalton; Amicon).
- the activity of the DMA dehydrogenase was determined analogously to the TMA dehydrogenase with a test approach as for the TMA dehydrogenase, except that 50 ⁇ l of a 100 M dimethylamine solution (in buffer) were provided instead of the TMA solution.
- the substrate spectrum was determined as indicated in Example 3F.
- the results showed that the enzyme shows a high specificity for DMA with regard to the amine component, trimethylamine is still reacted with 6% side activity and was inactive: methylamine, 2-dimethylaminoethylamine, dimethylformamide, formaldehyde and methanol.
- the enzyme is also apparently highly specific with regard to the electron acceptor, TMA is not converted if PES / DCPIP is caused by - -
- the reaction of DMA in the presence of PES / DCPIP is independent of ⁇ ; If a test is carried out under anaerobic conditions (buffer and test components gassed with argon for 15 min), an identical conversion rate is obtained as in the test with 0 2 gassed buffer. This distinguishes the enzyme from those in the group of oxidases in which 0 2 is the co-substrate of the reaction. Biochemically, the enzyme belongs to the group of dehydrogenases.
