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.
Sterile Filtered clear solution.
Y.Enterocolitica (O:9) YopE is supplied in 20mM HEPES buffer pH-7.6, 250mM NaCl and 20% glycerol.
