Posttranslational processing of methyl-accepting chemotaxis proteins in Escherichia coli.
Methyl-accepting chemotaxis proteins (MCPs) of Escherichia coli undergo changes in methylation state in response to chemical stimuli. The addition of methyl groups to MCP is dependent on cheR function; their removal is dependent on cheB function. This MCP methylation system is instrumental in establishing the unstimulated swimming pattern of E. coli and in enabling the cell to carry out sensory...
متن کاملSensory transduction in Escherichia coli: regulation of the demethylation rate by the CheA protein.
The reversible methylation of three membrane proteins plays an essential role in bacterial chemotaxis. Chemotactic stimuli bring about changes in the levels of methylation of these proteins, at least in part, by regulation of the demethylation reaction. Addition of attractants causes an increase in the methylation level and a transient, but essentially complete, inhibition in the rate of the de...
متن کاملTransduction in Escherichia Coli K-12.
SYSTEM of genetic transduction has been discovered in the sexually fertile A K-12 strain of Escherichia coli. This transduction is mediated by lambda, a temperate phage for which K-12 is normally lysogenic. The distinctive features of the lambda-K-12 system include the following: (1) The transductions are limited to a cluster of genes for galactose fermentation. The GaZ loci are closely linked ...
متن کاملThe Relationships of Sensory Processing Sensitivity and Information Processing Styles to Clinical Symptoms in Drug-Dependent Individuals
Objective: The aim of this study was to examine the roles of sensory processing sensitivity and information processing styles in predicting clinical symptoms in drug-dependent individuals. Method: The current study was correlational-descriptive. The statistical population included all drug-dependent individuals referred to addiction treatment centers in Tabriz. Among them, 290 people were selec...
