Entry
Name
bacteriochlorophyll a synthase;
bchG (gene name)
Class
Transferases;
Transferring alkyl or aryl groups, other than methyl groups;
Transferring alkyl or aryl groups, other than methyl groups (only sub-subclass identified to date)
BRITE hierarchy
Sysname
geranylgeranyl-diphosphate:bacteriochlorophyllide-a geranylgeranytransferase
Reaction(IUBMB)
geranylgeranyl diphosphate + bacteriochlorophyllide a = geranylgeranyl-bacteriochlorophyllide a + diphosphate [RN:
R11514 ]
Reaction(KEGG)
Substrate
geranylgeranyl diphosphate [CPD:
C00353 ];
bacteriochlorophyllide a [CPD:
C18155 ]
Product
geranylgeranyl bacteriochlorophyllide a [CPD:
C21217 ];
diphosphate [CPD:
C00013 ]
Comment
The enzyme catalyses the addition of a geranylgeranyl hydrophobic chain to bacteriochlorophyllide a via an ester bond with the 17-propionate residue. The side chain is later modified to a phytyl chain, resulting in bacteriochlorophyll a.
