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.
Cofactor
iron-sulfur
History
Reactions
2 S-adenosyl-L-methionine + a bacteriochlorophyllide c + H(2)O = a bacteriochlorophyllide e + 2 5′-deoxyadenosine + 2 L-methionine.
