Regulation of invertase synthesis by glucose in Saccharomyces cerevisiae.

RESUMO
Saccharomyces cerevisiae growing under repressible conditions (1% of glucose or more) produces a burst of external invertase when shifted to higher temperatures. The secretion of this invertase requires protein synthesis, but was found to be independent of RNA formation. The level of mRNA accumulated and translated was inversely proportional to the glucose present in the growth medium. These results are consistent with the hypothesis that invertase is continuously synthesized both in the presence and absence of glucose, but under repressible conditions is degraded before secretion takes place.
