Inhibition of growth of Rhizobium japonicum by cyclic GMP. 1985

B L Jones, and A K Agarwal, and D L Keister

Exogenous cyclic guanosine-3',5'-monophosphate (cGMP) inhibited the growth of Rhizobium japonicum at less than 100 microM. Other nucleotides, including cyclic AMP, cyclic IMP, and cyclic CMP, had no inhibitory effect even at higher concentrations nor was the inhibition by cGMP reversed by cyclic AMP. The inhibitory effect was independent of the carbon and nitrogen source(s) used. cGMP did not inhibit the growth of any other species of bacterium tested, including several fast-growing Rhizobium species. The kinetics of growth inhibition are multiphasic, with no apparent effect for several hours after addition, followed by a period of total inhibition. Subsequently, growth resumed at a slower rate. Resumption of growth was not due to destruction of the nucleotide. Studies of the intracellular cGMP concentration did not reveal significant changes in cells grown under aerobic or microaerobic conditions. No effect of cGMP on the derepression of respiratory nitrate reductase was observed.

D006152 Cyclic GMP Guanosine cyclic 3',5'-(hydrogen phosphate). A guanine nucleotide containing one phosphate group which is esterified to the sugar moiety in both the 3'- and 5'-positions. It is a cellular regulatory agent and has been described as a second messenger. Its levels increase in response to a variety of hormones, including acetylcholine, insulin, and oxytocin and it has been found to activate specific protein kinases.
