To investigate whether the production of acetate which occurs after exposure of respiring Saccharomyces cerevisiae cells to excess glucose can be reduced by overproduction of acetyl-CoA synthetase (ACS, EC 22.214.171.124), the ACS1 and ACS2 genes were introduced on multi-copy plasmids. For each isoenzyme, the level in glucose-limited chemostat cultures was increased by 3-6-fold, relative to an isogenic reference strain. However, ACS overproduction did not result in a reduced production of acetate after a glucose pulse (100 mmol l-1) to these cultures. This indicates that a limited capacity of ACS is not the sole cause of acetate accumulation in S. cerevisiae. Copyright (C) 1998 Federation of European Microbiological Societies.
