Cytosolic glycerol kinase (Gut1p) and mitochondrial glycerol-3-phosphate dehydrogenase (Gut2p) constitute the glycerol utilization pathway in Saccharomyces cerevisiae. Transcriptional analysis of the GUT2 gene showed that it was repressed by glucose and derepressed on the non-fermentable carbon sources, glycerol, lactate and ethanol. Derepression of GUT2 requires the protein kinase Snflp as well as the heteromeric protein complex, Hap2/3/4/5, and its putative DNA-binding site (UASHAP) located in the promoter region. Furthermore, glucose repression of GUT2 requires the negative regulator, Opi1p.
