S-腺苷-L-*轉移酶英文名稱:COMT;Catechol-O-methyl Transferase from porcine liver;Pyrocatechol-O-methyl Transferase;S-Adenosyl-L-methionine:catechol O-methyltransferase
其他名稱:兒茶酚氧位甲基轉移酶;兒茶酚-D-甲基轉移酶
級別:BR
活力:≥150units/mg protein
活力定義:One unit will produce 1.0 nanomole of total O-methylated products from 3,4 dihydroxyacetophenone per hour at pH 7.6 at 37℃C。Previous radioactive assay unit definition: One unit will catalyze the methylation of 1.0 nanomole of protocatechuic acid per hr at pH 7.9 at 37℃ using S-adenosyl-L-[methyl-14C]methionine as the methyl donor. (~6 radioactive units equal one new unit).
