EC 2.1.1.333

Accepted name: bacteriochlorophyllide d C-20 methyltransferase

Reaction: S-adenosyl-L-methionine + a bacteriochlorophyllide d = S-adenosyl-L-homocysteine + a bacteriochlorophyllide c

Other name(s): bchU (gene name)

Systematic name: S-adenosyl-L-methionine:bacteriochlorophyllide-d C-20 methyltransferase

Comments: The enzyme, found in green sulfur bacteria (Chlorobiaceae) and green flimentous bacteria (Chloroflexaceae), catalyses the methylation of the C-20 methine bridge position in bacteriochlorophyllide d, forming bacteriochlorophyllide c.
