Catalogue number



Outer membrane virulence protein YopE, yopE, yop25.


A main factor of pathogenic Yersinia enterocolitica strains is a plasmid-encoded type 3 secretion system, through which Yersinia outer proteins (Yops) are injected into the host cell. Yop E is a GTPase activation protein which controls pore formation by activating small Rho GTPase, causing inhibition of actin polymerization.


Recombinant Yersinia Enterocolitica (O:9) YopE in E.coli is a non-glycosylated, polypeptide chain having a calculated molecular mass of 24kDa.

Y.Enterocolitica (O:9) YopE is expressed with a -10x His tag at N-terminus and purified by proprietary chromatographic techniques.
