The synthesis and secretion of the toxic exoprotein e-haemolysin of E. coli PM152 is coded by the transmissible plasmid pHly152 (41 x 10 6 dalton) as shown by the transformation of the plasmid DNA and the isolation of mutants that are specifically altered in the synthesis and transport of haemolysin

As a first approach towards studying the regulation of hemolysin synthesis in Escherichia coli, we have fused lacZ into the four hly genes (hlyC, hlyA, hlyBa and hlyBb) using the Mud-1 (Mu::lacZ, Y, Apr) phage. The sites of insertion of Mud-1 within the various hly genes of the Hly plasmid pHly152 w

A sequence (hlyR) of about 600 bp which enhances the expression of hemolysin (HlyA) more than 50-fold was identified in the plasmid pHly152-specific hemolysin (hly) determinant. Deletion of this entire hlyR sequence led to the same low level of hemolysin synthesis and excretion as that expressed by

The sequence of three genes involved in cell division in E. coli has been determined to be ftsA-envA-azi by three-point transduction experiments. An ftsA envA double mutant strain forms filaments at the restrictive temperature of 42 degrees C, and not chains, but, like the chain forming envA parent
