Methylation of glutamate residues in membrane receptor-transducer proteins has generally been considered as a primary mechanism for adaptation in bacterial chemotaxis. Recent results indicate, however, that mutants completely lacking both the methylating and demethylating enzymes retain an ability to migrate in chemical gradients. This article presents a re-evaluation of the function of the chemoreceptor methylation reactions in light of these and other findings.
