Hexokinase-1

UniProtKB accession:  P05708

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the phosphorylation of various hexoses, such as D-glucose, D-glucosamine, D-fructose, D-mannose and 2-deoxy-D-glucose, to hexose 6-phosphate (D-glucose 6-phosphate, D-glucosamine 6-phosphate, D-fructose 6-phosphate, D-mannose 6-phosphate and 2-deoxy-D-glucose 6-phosphate, respectively) (PubMed:13211595, PubMed:5871820, PubMed:3579310). Mediates the initial step of glycolysis by catalyzing phosphorylation of D-glucose to D-glucose 6-phosphate (PubMed:13211595, PubMed:5871820). Involved in innate immunity and inflammation by acting as a pattern recognition receptor for bacterial peptidoglycan (By similarity). When released in the cytosol, N-acetyl-D-glucosamine component of bacterial peptidoglycan inhibits the hexokinase activity of HK1 and causes its dissociation from mitochondrial outer membrane, thereby activating the NLRP3 inflammasome (By similarity).
