Title Effects of galU mutation on flagellar formation in Escherichia coli.
Journal J Bacteriol
Abstract Two mutants of Escherichia coli strictly deficient in uridine-diphosphoglucose pyrophosphorylase activity (galU) were found to have very small numbers of flagellar filaments and hooks. In these mutants, both the rate of flagellin (flagellar protein) synthesis and the amount of messenger ribonucleic acid specific for flagellin were considerably lower than in the parental strains. Motile revertants from the galU mutants were isolated and were found to carry a suppressor mutation, which was mapped in the flaH cistron. These strains formed swarms under conditions of catabolite repression; their intracellular concentration of cyclic adenosine 5'-monophosphate was the same as that in the parental strains. These results suggest that the outer membrane affects flagellar formation through the flaH gene product.
