Abstract:
:sra5 mutations in Saccharomyces cerevisiae were previously shown to suppress the inefficient growth of ras2 strains on nonfermentable carbon sources and to result in deficient low-Km cyclic AMP (cAMP) phosphodiesterase activity. We have cloned SRA5 by complementation. It maps to the right arm of chromosome XV, tightly linked to PRT1, and its sequence matches the sequence of PDE2, encoding the low-Km cAMP phosphodiesterase. Disruptions of SRA5 allowed ras1 ras2 strains to grow either on rich media supplemented with cAMP or on minimal media without exogenous cAMP. sra5 strains failed to survive prolonged nitrogen starvation in the presence of exogenous cAMP.
