General Information | Comment | Organism |

evolution | the enzyme belongs to the PqqE-like rSAM protein family, part of the radical SAM domain superfamily. Members occur clustered with a well-conserved small polypeptide mycofactocin, similar in size to bacteriocins and PqqA, precursor of pyrroloquinoline quinone (PQQ). Partial phylogenetic profiling identifies the mycofactocin cluster. The mycofactocin precursor is modified by the gene Rv0693 family rSAM protein and other enzymes in its cluster. Rv0693 belongs to a branch of the radical SAM family in which known or presumed substrates are short peptides. The Rv0693 family radical SAM protein modifies the TIGR03969 family peptide to produce a bioactive molecule: a bacteriocin, a redox cofactor like PQQ, or a signaling metabolite such as Pep1357. The neighboring glycosyltransferase (Rv0696) likely also participates. Based on its near universal distribution in the genus Mycobacterium (among many other Actinobacteria), and analogy of its biosynthesis cluster to PQQ cofactor and bacteriocin biosynthesis clusters, the name mycofactocin is proposed for members of this family. Additional protein families co-cluster with the mycofactocin precursor, mycofactocin cluster-containing genomes and linked oxidoreductases, detailed overview | Mycobacterium tuberculosis |
