Putative glucokinase involved in phosphorylation of aldohexoses and glucose uptake (By similarity). Involved in sporulation. Required for the full activation of the early meiotic inducer IME1. ATP + D-glucose = ADP + D-glucose 6-phosphate + H(+) Carbohydrate degradation; glycolysis; D-glyceraldehyde 3-phosphate and glycerone phosphate from D-glucose: step 1/4. Repressed by glucose through the MIG1 and MIG2 repressors. Present with 10600 molecules/cell in log phase SD medium. Belongs to the hexokinase family.
