titleOfInvention | A kind of preparation method of urso and its alternation enzyme processed |
abstract | The present invention relates to a kind of 7 β steroid dehydrogenases of method and its preparation that urso is prepared using biological enzyme technology.This method is using 3 α hydroxyls, 7 oxo, 5 β cholanic acids as substrate, under the conditions of existing for NADP, glucose, glucose dehydrogenase and buffer solution, urso is prepared with 77 oxo of β steroid dehydrogenases 3 α hydroxyls of enzymatic, 5 β cholanic acids, wherein 7 β steroid dehydrogenases derive from Turneriella parva .This method is easy to operate, reaction condition it is gentle it is easily-controllable, the reaction time is short, to the high conversion rate of substrate up to more than 99.8%, the content of the product obtained is more than 98.5%. |
