Description

Novel microorganism, maltose phosphorylase and trehalose phosphorylase and manufacture method thereof
Technical field
The present invention relates to the manufacture method of novel microorganism, novel enzyme and novel enzyme.Specifically, the series bacillus that the present invention relates to have the throughput of necessary maltose phosphorylase and trehalose phosphorylase with the Production by Enzymes trehalose time belong to novel microorganism, the gene of the aminoacid sequence of the novel maltose phosphorylase that obtains by this microorganism and trehalose phosphorylase, encoding such enzymes and the manufacture method of these enzymes.
Background technology
Trehalose is expected to be widely used in fields such as pharmaceuticals, makeup and food, has carried out many trials in order to carry out industrial production in the past.These technology can roughly be divided into following three classes.The first from trehalose can be accumulated in endobacillary microorganism extract and the method for refining this material (for example, with reference to J.Am.Chem.Soc.72 volume, 2059 pages, nineteen fifty; No. 266584 communique of German Patent; Te Kaiping 3-130084 communique; Te Kaiping 5-91890 communique; Te Kaiping 5-184353 communique and spy open flat 5-292986 communique).This method comprises the cultivation operation, separation circuit of microorganism, extracts the refining crystallization operation of the trehalose of the operation of trehalose, extraction from microorganism, and the manufacturing process of trehalose is quite complicated.And not only the productivity of trehalose is low, and has also produced a large amount of microorganism extraction residues as waste, so can not be called economical efficiency method preferably.
And, also developed produce trehalose fermentation method (for example, open flat 5-211882 communique with reference to the spy), in this method, the microorganism of cultivating brevibacterium sp (Brevibacterium) and Corynebacterium (Corynebacterium) etc. is as the microorganism that produces trehalose outside thalline.Yet in this method, the rate of accumulation of trehalose in substratum is lower, only is about 3% (w/v), at industrial mass production trehalose, needs big volumetrical fermentor tank and the purification apparatus that matches of scale with it, therefore has problems at economic aspect.And, in this method, not only need to carry out sterilization, but also need remove when cultivating numerous and diverse operation by inclusion that uses bacterial strain to produce or medium component etc. in order to obtain the purified trehalose.
On the other hand, also developed enzyme process in order to solve the variety of issue that exists in these fermentation methods.Promptly, orthophosphoric acid salt β-D-glucanotransferase) and derive from the trehalose phosphorylase (α of algae in the presence of phosphoric acid, will derive from the maltose phosphorylase (maltose: of microorganism, α-trehalose: orthophosphoric acid salt β-D-glucanotransferase) act on maltose and produce the method for trehalose (for example, with reference to No. 1513517 communique of Japanese Patent; Agric.Biol.Chem., 49 volumes, 2113 pages, 1985), orthophosphoric acid salt alpha-D-glucose based transferase) and derive from the trehalose phosphorylase (α of basidiomycetes with the sucrose phosphorylase that in the presence of phosphoric acid, will derive from bacterium (sucrose:, α-trehalose: orthophosphoric acid salt alpha-D-glucose based transferase) act on the method (for example, with reference to putting down into 6 years Japanese chemurgy meeting conference lecture summary collection 3Ra14) that sucrose obtains trehalose.Can generate trehalose with 60%~70% higher yields from maltose or sucrose according to these methods.And, owing to used high purity sugar after refining,, to compare with additive method so the trehalose that obtains by enzyme reaction also is easy to make with extra care as raw material, this method is considered to industrial useful method.Yet, employed enzyme in these methods, particularly the source of trehalose phosphorylase only limits to euglena (Euglena) or fine and soft (Grifola frondosa) such algae or the basidiomycetes of dance, not only have problems in order stably to produce enzyme at economic aspect, also have any problem at technical elements. and, the trehalose phosphorylase that obtains, be mated the sucrose phosphorylase of use, the dimensional discrepancy of optimal pH separately of maltose phosphorylase is bigger, and it is also very low to the stability of temperature, can only under 25 ℃~37 ℃ cold condition, carry out the formation reaction of trehalose. the problem of Cun Zaiing is like this, not only when being used two kinds of enzymes, make the control of pH become difficult, and because temperature of reaction is low, when using opening reactive tank to carry out enzyme reaction, can cause the pollution of assorted bacterium, for the side reaction that prevents to bring thus also needs strict hygiene control. and, when being used these known enzymes, because these enzymes have the concentration of substrate dependency, thereby can't use the raw material of high density. therefore, these methods can not be called as the good method of economical efficiency.
In addition, also delivered the method for making trehalose with the amylolysis thing as substrate.According to this method, to be used for generating malt oligosaccharide based mycose that end has the non-reducing sugar of trehalose structure generates enzyme (Maltooligosyl-Trehalose synthase) and is used for acting on the amylolysis thing from this non-reducing sugar specificity dissociate trehalose resolvase of trehalose, high yield with 80% generates trehalose by starch and (for example, opens flat 7-143876 communique with reference to the spy; European patent application 628630A2 specification sheets; This chemurgy of order can be given a lecture summary collection, p31 (1995)).Yet, in this method,, being difficult to make described enzyme immobilization and flowing through substrate owing to use starch as substrate, the further manufacturing of reactor etc. is difficult to oversimplify and efficient activity.And the operation of the purging liquid that obtains behind the trehalose crystallization being carried out saccharification more also is difficult to construct.
From the above mentioned, as long as can find to make and make with extra care easy, have higher thermostability and do not have dependent novel maltose phosphorylase of concentration of substrate and trehalose phosphorylase, be that the high yield of raw material is made trehalose simply efficiently with regard to being expected to the maltose that can obtain simply in a large number.
So, first purpose of the present invention is to solve the variety of issue in the described conventional art, providing can the High-efficient Production maltose phosphorylase and the novel microorganism of trehalose phosphorylase, and described maltose phosphorylase and trehalose phosphorylase are the novel enzymes that can satisfy above-mentioned various requirement.Second purpose of the present invention be to provide make and refining easy, have higher thermostability and do not have dependent novel maltose phosphorylase of concentration of substrate and trehalose phosphorylase.And the 3rd purpose of the present invention is to provide the manufacture method of maltose phosphorylase and/or trehalose phosphorylase, in the method, uses described microorganism can obtain above-mentioned two kinds of enzymes simple and effective.
