htpR-like gene controls cell division and proteolysis in Pseudomonas aeruginosa.

As shown in hybridization experiments, the genome of Pseudomonas aeruginosa cells contains a htpR-like gene which controls the expression of heat shock genes in cells of Escherichia coli. By means of specially constructed plasmids, the synthesis of htpR antisense RNA has been found to disturb cell division and proteolytic processes in P. aeruginosa, suggesting the functional relationship of htpR genes in E. coli and Pseudomonas bacteria.
