Abstract
Provided are a glycosyltransferase UGT76G1 mutant, an isolated polynucleotide, a carrier, a production method, and a composition and a kit for the glycosylation of substrates. Further provided are a method for increasing the catalytic activity of the glycosyltransferase UGT76G1 mutant, and a method for promoting the glycosylation of flavone compounds and the use thereof. The glycosyltransferase UGT76G1 mutant is subjected to mutations at positions corresponding to positions 87, 199, 204 or 379 of SEQ ID NO: 1, and significantly improves the transformation activity of substrates of the flavone compounds.
