Pyrroloquinoline quinone (PQQ) is a small, redox-active molecule that serves as a cofactor for several bacterial dehydrogenases, introducing pathways for carbon utilization that confer a growth advantage. Early studies had implicated a ribosomally translated peptide as the substrate for PQQ production. This study presents a sequence and structure based analysis of the components of the pqq operon. We find the necessary components for PQQ production are present in 126 prokaryotes, most of which are Gram- negative and a number of which are pathogens. A total of five gene products, PqqA, PqqB, PqqC, PqqD and PqqE, are concluded to be obligatory for PQQ production. Three of the gene products in the pqq operon, PqqB, PqqC and PqqE, are members of large protein superfamilies. By combining evolutionary conservation patterns with information from three-dimensional structures, we are able to differentiate the gene products involved in PQQ biosynthesis from those with divergent functions. The observed persistence of a conserved gene order within analyzed operons strongly suggests a role for protein/protein interactions in the course of cofactor biosynthesis. These studies propose previously unidentified roles for several of the gene products as well as possible new targets for antibiotic design and application.
