Enzyme Information
| 2.1.1.333 |
Bacteriochlorophyllide d C-20 methyltransferase.
based on mapping to UniProt Q8KGE0
S-adenosyl-L-methionine + a bacteriochlorophyllide d = S-adenosyl-homo-L- homocysteine + a bacteriochlorophyllide c.
-!- The enzyme, found in green sulfur bacteria (Chlorobiaceae) and green flimentous bacteria (Chloroflexaceae), catalyzes the methylation of the C-20 methine bridge position in bacteriochlorophyllide d, forming bacteriochlorophyllide c.
