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
