Compensatory mutations in receptor function: a reevaluation of the role of methylation in bacterial chemotaxis.
Compensatory mutations in receptor function: a reevaluation of the role of methylation in bacterial chemotaxis.
During bacterial chemotaxis membrane receptor proteins are methylated and demethylated at glutamate residues. The generally accepted view is that these reactions play an essential role in the chemosensing mechanism. Strains may be isolated, however, that exhibit chemotaxis in the complete absence of methylation. These are readily obtained by selecting for …
