Yersinia pestis (Y. pestis; formerly Pasteurella pestis) is a gram-negative, non-motile, coccobacillus bacterium without spores that is related to both Yersinia enterocolitica and Yersinia pseudotuberculosis, the pathogen from which Y. pestis evolved [1] [2] and responsible for the Far East scarlet-like fever.
In molecular biology, YopR is a protein domain commonly found in gram negative bacteria, in particular Yersinia and is a core domain. Proteins in this entry are type III secretion system effectors. They are named differently in different species and in Yersinia has been designated YopR (Yersinia outer protein R) which is encoded by the YscH ...
YopH from Yersinia sp. is essential for pathogenesis, as it allows the bacteria to resist phagocytosis by host macrophages through its ability to dephosphorylate host proteins, thereby interfering with the host signalling process. Yersinia has one of the most active PTP enzymes known.
The Yersiniaceae are a family of Gram-negative bacteria that includes some familiar pathogens. For example, the type genus Yersinia includes Yersinia pestis, the causative agent of plague. This family is a member of the order Enterobacterales in the class Gammaproteobacteria of the phylum Pseudomonadota. [1]
YopE is an effector protein of the bacteria Yersinia. It functions as a Rho GTPase-activating protein (GAP). YopE acts as both a virulence factor and a protective antigen. In order to evade detection by the host, YopE uses a number of different eukaryotic signalling pathways to counteract innate and adaptive immune responses of the host.
YadA is found in three pathogenic species of Yersinia, Y. pestis, Y. pseudotuberculosis, and Y. enterocolitica. The YadA domain is encoded for by a virulence plasmid in Yersinia, which encodes a type-III secretion (T3S) system consisting of the Ysc injectisome and the Yop effectors. [1]
Yersinia is a genus of bacteria in the family Yersiniaceae. [1] Yersinia species are Gram-negative, coccobacilli bacteria, a few micrometers long and fractions of a micrometer in diameter, and are facultative anaerobes. [2] Some members of Yersinia are pathogenic in humans; in particular, Y. pestis is the causative agent of the plague.
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 ...
