Upon incubation at 37 degrees C in the absence of Ca2+ ions, pathogenic strains of the genus Yersinia cease growing and produce large amounts of a series of plasmid-encoded proteins involved in pathogenicity. These proteins, called Yops (for Yersinia outer membrane proteins), are detected in both the outer membrane fraction and the culture supernatant. We present here the nucleotide sequence of genes yop20 and yop25 from Yersinia enterocolitica O:9. Protein Yop25 is very similar to YopE, the corresponding protein from Yersinia pestis, Y. pseudotuberculosis, and Y. enterocolitica O:8 (A. For…
