ENZYME entry: EC 2.1.1.332

Accepted Name
Bacteriochlorophyllide d C-8(2)-methyltransferase.
Reaction catalysed
  • S-adenosyl-L-methionine + 8,12-diethyl-3-vinylbacteriochlorophyllide d <=> S-adenosyl-L-homocysteine + 12-ethyl-8-propyl-3-vinylbacteriochlorophyllide d
  • S-adenosyl-L-methionine + 12-ethyl-8-propyl-3-vinylbacteriochlorophyllide d <=> S-adenosyl-L-homocysteine + 12-ethyl-8-isobutyl-3-vinylbacteriochlorophyllide d
Cofactor(s)
Iron-sulfur.
Comment(s)
  • This enzyme, found in green sulfur bacteria (Chlorobiaceae) and green flimentous bacteria (Chloroflexaceae), is a radical S-adenosyl-L- methionine (AdoMet) enzyme.
  • It adds one or two methyl groups at the C-8(2) 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.
