Abstract
The GUT1 gene of Saccharomyces cerevisiae, encoding glycerol kinase, was cloned and sequenced. The cloned genomic DNA fragment contains an open reading frame potentially coding for a protein of 709 amino acids with homology to bacterial glycerol kinases (40.8% identity over 502 amino acids, and 42.1% identity over 496 amino acids, in comparison to the smaller E. coli and B. subtilis enzymes). Disruption of GUT1 showed that the gene is required for growth on glycerol, but not on glucose or ethanol media. No glycerol kinase activity was detected in the disruption mutant. According to enzyme activity and transcript analysis, synthesis of glycerol kinase is repressed by glucose, and derepression is ADR1-dependent.
