Enzyme that catalyses the transfer of phosphate from ATP to glucose to form glucose-6-phosphate, the first reaction in the metabolism of glucose via the glycolytic pathway.
A hexokinase is an enzyme that phosphorylates hexoses (six-carbon sugars), forming hexose phosphate. In most organisms, glucose is the most important substrate of hexokinases, and glucose-6-phosphate the most important product. Hexokinases should not be confused with glucokinase, which is a specific isoform of hexokinase. While other hexokinases a...Found on http://en.wikipedia.org/wiki/Hexokinase
