| Accepted name: | bacteriochlorophyllide d C-82-methyltransferase | ||
| Reaction: | (1) S-adenosyl-L-methionine + 8,12-diethyl-3-vinylbacteriochlorophyllide d = S-adenosyl-L-homocysteine + 12-ethyl-8-propyl-3-vinylbacteriochlorophyllide d (2) S-adenosyl-L-methionine + 12-ethyl-8-propyl-3-vinylbacteriochlorophyllide d = S-adenosyl-L-homocysteine + 12-ethyl-8-isobutyl-3-vinylbacteriochlorophyllide d |

| Systematic name: | S-adenosyl-L-methionine:8,12-diethyl-3-vinylbacteriochlorophyllide-d C-82-methyltransferase | ||
| Comments: | This enzyme, found in green sulfur bacteria (Chlorobiaceae) and green flimentous bacteria (Chloroflexaceae), is a radical S-adenosyl-L-methionine (AdoMet) enzyme and contains a [4Fe-4S] cluster. It adds one or two methyl groups at the C-82 position of bacteriochlorophylls of the c, d and e types. These methylations play a role in fine-tuning the structural arrangement of the bacteriochlorophyll aggregates in chlorosomes and therefore directly influence chlorosomal absorption properties. | ||
