产品内容
本酶催化的反应为2 S-Adenosyl-L-Methionine + A Bacteriochlorophyllide C + H2O = A Bacteriochlorophyllide E + 2 5'-Deoxyadenosine + 2 L-Methionine (Overall Reaction);;(1a) S-Adenosyl-L-Methionine + A Bacteriochlorophyllide C + H2O = A 7-(Hydroxymethyl)bacteriochlorophyllide C + 5'-Deoxyadenosine + L-Methionine;;(1b) S-Adenosyl-L-Methionine + A 7-(Hydroxymethyl)bacteriochlorophyllide C + H2O = A 7-(Dihydroxymethyl)bacteriochlorophyllide C + 5'-Deoxyadenosine + L-Methionine;;(1c) A 7-(Dihydroxymethyl)bacteriochlorophyllide C = A Bacteriochlorophyllide E + H2O (Spontaneous)，系统名称为Bacteriochlorophyllide-C:S-Adenosyl-L-Methionine Oxidoreductase (C-71-Hydroxylating)，该酶存在于绿硫细菌（绿菌科）中，是一种自由基S-腺苷-L-甲硫氨酸（AdoMet）酶，含[4Fe-4S]簇。它催化细菌脱镁叶绿素c C-7甲基的两个连续羟化反应，形成偕二醇中间体，后者自发脱水产生细菌脱镁叶绿素e的甲酰基。
