Abstract

The DNA sequence was determined for a region upstream of thepuf operon ofRhodospirillum rubrum. A partial ORF was identified. The DNA sequence and the inferred amino acid sequences were aligned with those ofbchA ofRhodobacter capsulatus and other phototrophic bacteria. Based on this alignment and genetic evidence, this ORF was identified asR. rubrum bchA, which encodes an enzyme involved in bacteriochlorophyll biosynthesis. An additional ORF was identified in the intergenic region betweenbchA andpufB. Sequences possibly having a role inpuf expression were identified.
