Proteogenomic discovery of sORF-encoded peptides associated with bacterial virulence in Yersinia pestis

Shiyang Cao, Xinyue Liu, Yin Huang, and Yanfeng Yan et al. utilized an integrated proteogenomic approach to describe an atlas of small open reading frame-encoded peptides (SEPs) in the pathogen, Yersinia pestis. They demonstrate that two of these SEPs are associated with regulation of bacterial virulence, and altogether develop a valuable resource for future research into Y. pestis physiology.
