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.

the enzyme-deficient mutant of Rhodobacter sphaeroides, BG1 strain, is photosynthetically incompetent. The function can be restored by I44F mutant chlorophyll synthase of Synechocystis sp. PCC 6803

comparison of BchG gene sequences from Chloroflexus aurantiacus, Chloronema sp., and Roseiflexus castenholzii HL08. All deduced amino acid sequences show a highly conserved region, which includes the motif DRXXD, characteristic of polyprenyltransferases, which is extended to DREVDAINEP for green sulfur bacteria

the mutant shows chlorophyll synthase activity. The mutation does not affect the Km value for the original substrate, bacteriochlorophyllide a, but the Km value for the new substrate chlorophyllide a is about 18fold larger than those for the original substrate
