Yersinia pestis
In molecular biology, LcrV is a protein found in "Yersinia pestis" and several other bacterial species. It forms part of the "Yersinia pestis" virulence protein factors that also includes all Yops, or "Yersinia" outer protein, but the name has been kept out of convention. LcrV's main function is not actually known, but it is essential for the production of other Yops.
