KEGG   ENZYME: 2.1.1.333
Entry
EC 2.1.1.333                Enzyme                                 
Name
bacteriochlorophyllide d C-20 methyltransferase;
bchU (gene name)
Class
Transferases;
Transferring one-carbon groups;
Methyltransferases
Sysname
S-adenosyl-L-methionine:bacteriochlorophyllide-d C-20 methyltransferase
Reaction(IUBMB)
S-adenosyl-L-methionine + a bacteriochlorophyllide d = S-adenosyl-L-homocysteine + a bacteriochlorophyllide c [RN:R09063]
Reaction(KEGG)
R09063
Substrate
S-adenosyl-L-methionine [CPD:C00019];
bacteriochlorophyllide d [CPD:C18160]
Product
S-adenosyl-L-homocysteine [CPD:C00021];
bacteriochlorophyllide c [CPD:C18161]
Comment
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.
