Abstract

The intracellular concentration of cyclic AMP reached a maximum in 3.5-day old cultures of Mycobacterium smegmatis grown in the presence of glycerol as the main source of carbon. Glucose-grown cells exhibited decreased cyclic AMP levels at all stages of growth. When M. smegmatis cells were incubated with various metabolites, pyruvate increased whereas glucose, citric acid, succinic acid and lactic acid decreased intracellular cyclic AMP levels. No cyclic AMP was detected in the incubation medium. The presence of a cyclic AMP-binding protein was demonstrated in cellfree extracts of M. smegmatis.
