Abstract excerpt
Mutational damage of the ptsH gene leads to pleiotropic disturbance of sugar utilization in Escherichia coli K12. A fruS mutation suppresses the defect because of a constitutional expression of the fruB and fruA genes. FruB protein possessing a pseudo-HPr activity replaces the HPr. It was shown that wild type allele fruS+ dominates over the fruS1156 mutation in heterozygous merodiploid. The existence of...
