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.
