Genome-Based Characterization of a Plasmid-Associated Micrococcin P1 Biosynthetic Gene Cluster and Virulence Factors in Mammaliicoccus sciuri IMDO-S72.

ABSTRACT: Analysis of the de novo assembled genome of Mammaliicoccus sciuri IMDO-S72 revealed the genetically encoded machinery behind its earlier reported antibacterial phenotype and gave further insight into the repertoire of putative virulence factors of this recently reclassified species. A plasmid-encoded biosynthetic gene cluster was held responsible for the antimicrobial activity of M. sciuri IMDO-S72, comprising genes involved in thiopeptide production. The compound encoded by this gene cluster was structurally identified as micrococcin P1. Further examination of its genome highlighted the ubiquitous presence of innate virulence factors mainly involved in surface colonization. Determinants contributing to aggressive virulence were generally absent, with the exception of a plasm
