Abstract

Pseudomonas aeruginosa has a choline uptake system which is expressed in bacteria grown in the presence of succinate and ammonium chloride as the carbon and nitrogen source, respectively. This system obeys Michaelis-Menten kinetics with an apparent Km value of 53 microM; its activity is not inhibited by high osmolarities in the medium but is partially inhibited by choline metabolites such as betaine and dimethylglycine.
