Nitrogen catabolite repression in Saccharomyces cerevisiae during wine fermentations.
FEMS Yeast Res. 2004 Mar; 4(6):625-32.FY

Abstract

We carried out fermentations with several nitrogen sources in different concentrations and studied nitrogen regulation by following the transcriptional profile of the general amino-acid permease (GAP1) and the ammonium permeases (MEP1, MEP2, MEP3). In wine fermentations the cells evolve from a nitrogen-repressed situation at the beginning of the process to a nitrogen-derepressed situation as the nitrogen is consumed. These nitrogen-repressed/derepressed conditions determined the different patterns of ammonium and amino-acid consumption. Arginine and alanine were hardly used under the repressed conditions, while the uptake of branched-chain and aromatic amino acids increased.
