An O-Mehtyltransferase mutant and a method for producing 3,7-O-dimethylquercetin and 3,7-O-dimethylkaempferol using the same

摘要

The present invention O-Mehtyltransferase mutants and using the same 3,7-O-dimethylquercetin, and 3, relates to a method for producing a 7-dimethylkaempferol, more particularly, to 7-O-methyltransferase gene by the mutant by random mutagenesis have a conventional non- active 3-O-methyltransferase activity by using this mutant to 3,7 -O-dimethylquercetin, and to a 3,7-O-dimethylkaempferol to a method of manufacturing .
