The invention discloses artificial bear gall powder and a preparation method thereof. The preparation method comprises the following steps: step (a) dissolving livestock gall powder by using a buffer solution of which the pH value is equal to 7-9 and then filtering to obtain filter residues and a filtrate; step (b) adding the filtrate into a reactor filled with 7alpha-hydroxyl steroid dehydrogenase, 7beta-hydroxyl steroid dehydrogenase and coenzyme I or coenzyme II and reacting; step (c) after the reaction ends, freeze-drying a reaction liquid and then mixing the freeze-dried reaction liquid with the filter residues to obtain the artificial bear gall powder. According to the preparation method disclosed by the invention, completely natural livestock gall is taken as a raw material for preparing the artificial bear gall, no other chemical substances are added, common animal gall is adopted and a gall source is easy to pick, obtain and process; through an in-vitro enterohepatic circulation simulation process, the livestock gall is biologically transformed into the artificial bear gall powder which is equivalent to natural bear gall powder in chemistry, and the artificial bear gall powder is used as a natural bear gall replacement to protect the endangered animal Asian black bear and promote healthy development of the bear gall industry.

The invention provides a mutant of 7 beta-hydroxyl steroid dehydrogenase, application of the mutant and a synthesis method. The mutant of the 7 beta-hydroxyl steroid dehydrogenase is characterized in that amino acid sequences of the mutant are Seq ID NO:4, and coded nucleotide sequences are Seq ID NO:3; or amino acid sequences of the mutant are Seq ID NO:6, and coded nucleotide sequences are Seq ID NO:5. The mutant, the application and the synthesis method have the advantages that cholic acid compounds, particularly ursodeoxycholic acid, can be catalytically synthesized by the efficient 7 beta-hydroxyl steroid dehydrogenase, mutant enzymes of the 7 beta-hydroxyl steroid dehydrogenase and coenzyme regeneration systems, accordingly, the substrate concentration can reach 100 g/L, the conversion rate is 99.2-99.5%, and the weight yield can reach 94-96%; and the enzymes can be inexpensively and easily obtained by the aid of a fermentation process, accordingly, the production cost and the product quality are superior to the production cost and the product quality of chemical synthesis methods, and the mutant and the synthesis method are applicable to industrial production.
