| Abstract: | A set of isogenic derivatives of Yersinia pestis EV strain was obtained including the variants harbouring the different compositions of Yersinia own plasmids. The protein profiles of outer membranes of the set of strains were defined. The polyacrylamide gel electrophoresis has shown the small 6.1 Md plasmid to code an outer membrane protein with mol mass 29 kDa, different from pesticin I, while the heavy 60.0 Md plasmid encodes the 15-16 kDa polypeptide different from monomers of F1 and T-antigens of plague microbe. |
