This image is a scaled-down version of the actual pathway image. It does not contain any links to the protein information pages.


Y. pestis (Yersinia pestis) is rod shaped, Gram-negative, and non-motile but has two distinct flagellar gene clusters; one set is incomplete and the other produces a truncated protein, which acts as a transcriptional activator for the flagellar genes. Y. pestis, a Group-A bioterrorism agent, causes Plague, a re-emerging zoonotic disease transmitted to humans through flea bites and typically characterized by the appearance of a tender and swollen lymph node, the bubo. It is believed that Y. pestis is a clone that evolved from Y. pseudotuberculosis (Yersinia pseudotuberculosis) about 1.5 to 20 thousand years ago. Y. pestis is primarily a rodent pathogen, with humans being an accidental host when bitten by an infected rat flea (Ref.1). The rodents’ fleas, such as [...]
