FIG 7.

Multiple-sequence alignment of known and putative (indicated by source organisms) subgroup II circular bacteriocin precursors using Clustal W (36). The known circular bacteriocins are acidocin B, gassericin A, and butyrivibriocin AR10. The UniProt accession numbers are in parentheses. The region corresponding to leader peptide sequences is underlined, and the highly conserved asparaginyl cleavage site is marked by an asterisk. Conserved residues (similarity threshold of 80%) are highlighted in black.
