DE   bacteriochlorophyll a synthase.
CA   (2E,6E,10E)-geranylgeranyl diphosphate + bacteriochlorophyllide a + H(+)
CA   = diphosphate + geranylgeranyl-bacteriochlorophyllide a.
CC   -!- The enzyme catalyzes the addition of a geranylgeranyl hydrophobic
CC       chain to bacteriochlorophyllide a via an ester bond with the
CC       17-propionate residue.
CC   -!- The side chain is later modified to a phytyl chain, resulting in
CC       bacteriochlorophyll a.
