Systematic name: | bacteriochlorophyllide-c:S-adenosyl-L-methionine oxidoreductase (C-71-hydroxylating) | ||||
Comments: | The enzyme, found in green sulfur bacteria (Chlorobiaceae), is a radical S-adenosyl-L-methionine (AdoMet) enzyme and contains a [4Fe-4S] cluster. It catalyses two consecutive hydroxylation reactions of the C-7 methyl group of bacteriochlorophyllide c to form a geminal diol intermediate that spontaneously dehydrates to produce the formyl group of bacteriochlorophyllide e. | ||||
