schemaClass Summation
text Cytosolic hexokinase 1 (HK1), together with isoforms HK2 and 3 and glucokinase (GCK), catalyse the irreversible reaction of alpha-D-glucose (Glc) and ATP to form alpha-D-glucose-6-phosphate (G6P) and ADP, the first step in glycolysis. HK1 is the predominant isoform of the different HKs in tissues that utilise glucose for their physiological function such as brain, lymphocytes, erythrocytes, platelets and fibroblasts. Defects in HK1 can cause hexokinase deficiency (HK deficiency; MIM:235700), a rare, autosomal recessive disease with nonspherocytic hemolytic anemia as the predominant clinical feature (Kanno 2000).
