Lanthipeptides constitute a major family of ribosomally synthesized and post-translationally modified peptides (RiPPs). They are classified into four subfamilies based on the characteristics of their lanthipeptide synthetases. While over a hundred lanthipeptides have been discovered to date, very few of them are class IV lanthipeptides and the latter are all structurally similar. Here, we identified an uncharacterized group of class IV lanthipeptides using bioinformatics analysis. One representative pathway from Streptomyces sp. NRRL S-1022 was expressed in Escherichia coli, which generated a lanthipeptide with two non-overlapping rings that has not been reported for known class IV lanthipeptides. Further investigation into the biosynthetic mechanism revealed that multiple modification pathways are in operation in which dehydration and cyclization occur in parallel. While peptidases for maturation of class IV lanthipeptides have been elusive, two aminopeptidases encoded in the genome of Streptomyces sp. NRRL S-1022 were shown to process the modified peptide by the dual endopeptidase/aminopeptidase activity. This work opens doors to discover more class IV lanthipeptides with interesting structural features and biological activities.
