putative peptide modification target, TIGR04139 family This model describes a rare family of small putative polypeptides, including three encoded in tandem in Sphingobacterium spiritivorum ATCC 33300, in the vicinity of a TIGR04085 protein. This pairing is conserved in Chryseobacterium gleum ATCC 35910, Kordia algicida OT-1, and other species. TIGR04085 describes a C-terminal additional 4Fe4S-binding domain in PqqE and other radical SAM enzymes that seems to be a marker for peptide modification, and the family modeled here is a candidate modified peptide precursor. |
