3',5'-cyclic adenosine monophosphate-requiring mutants of Escherichia coli.

Y Onishi, L Silengo, M Kuwano, D Schlessinger.

Abstract

Mutants that require exogenous 3',5'-cyclic adenosine monophosphate (cAMP) for exponential growth were isolated from strains deficient in adenyl cyclase. Studies of one strain showed that cAMP is not incorporated into macromolecules; instead, it seems to have a regulatory function, i.e., in media lacking cAMP, cells form ribonucleic acid (RNA) and protein at linear rather than exponential rates. The exact lesion is not known; ribosomes, messenger RNA, and the beta and beta' subunits of RNA polymerase continue to be made in absence of added cAMP.
