Gcr1p and Gcr2p are transcriptional activators of glycolytic genes in Saccharomyces cerevisiae (4,5). Gcr1p is a DNA-binding protein interacting with the consensus sequence CTTCC, whereas Gcr2p interacts with Gcr1p (6,2). Both factors are needed for normal transcriptional activation (7,8). Null and point mutants have decreased levels of most of the glycolytic enzymes (1,9,10). The gcr1 mutant of yeast grows at near wild-type rates on nonfermentable carbon sources but exhibits a severe growth defect when grown in the presence of glucose, even when nonfermentable carbon sources are available (10). The human gene, hSGT1, can substitute for GCR2 but not GCR1 (11).
