摘要:
The present invention relates to a hybrid enzyme comprising at least one carbohydrate-binding module amino acid sequence and at least the catalytic module of a glucoamylase amino acid sequence. The invention also relates to the use of the hybrid enzyme in starch processing and especially ethanol production.
摘要:
Stabilized bromine solutions are prepared by combining a bromine source and a stabilizer to form a mixture, adding an oxidizer to the mixture, and then adding, an alkaline source to adjust the pH of the mixture to at least 13.
摘要:
A method of converting olefins to chiral epoxides comprises combining an asymmetric aliphatic or aryl alkene substrate with a buffered chloroperoxidase solution to form a stabilized reaction mixture, and gradually adding hydrogen peroxide as a substrate oxidant, such that the chloroperoxidase catalyzes the conversion of the substrate to the corresponding epoxide in enantiomeric excess. The products of the invention are alkyl and aryl non-primary epoxides. The resulting preparations are enantiomerically pure, and may greatly enhance large-scale synthesis of stereoisomer products such as pharmaceuticals and pesticides.
