[Mutual effect of invertase and acid phosphatase from the yeast Saccharomyces cerevisiae on their secretion into culture media].

The hypothesis that various extracellular enzymes produced by the yeast Saccharomyces cerevisiae exert a mutual influence on their secretion into the culture medium was tested experimentally. The statistically processed results indicate that extracellular invertase affects the secretion of acid phosphatase, and acid phosphatase affects the secretion of invertase. In addition, the secretion of each of these enzymes was shown to be subject to autoregulation.
