[Cloning of Yersinia pseudotuberculosis calcium-dependence plasmid pYV6953 BamHI fragments and their analysis in Escherichia coli mini-cells].
Calcium dependence plasmid pYV6953 (70.4 kb) in Yersinia pseudotuberculosis cells codes for the major quantities synthesis of 150; 48.5; 19.4 Kd outer membrane proteins and the 51, 38, 27 Kd proteins secreted into the culturing medium. These outer membrane and secreted proteins are synthesized in considerable amounts in Yersinia pseudotuberculosis strains 6953 and 9547 at 37 degrees C and in the absence of calcium ions in the culturing medium. BamHI fragments of the plasmid pYV6953 as components of the recombinant plasmids code for the synthesis of 150; 66.6; 51; 48.5; 47; 38 and 21.5 Kd proteins in Escherichia coli mini cells. The synthesis of 150 and 48.5 Kd proteins is determined by the BamHI fragment 9 of the plasmid pYV6953 (3.3 kb). Addition of up to 8% of ethanol inhibiting the protein synthesis eliminates the 150 Kd protein but not the 48.5 Kd synthesis. The 48.5 Kd protein is concluded to be a subunit of the 150 Kd protein. The plasmid pYV6953 is different from the known plasmids pIB1 and pCD1 plasmids as far as the outer membrane and secreted proteins coded by the plasmids are concerned.
