Hexokinase

A picture of hexokinase 1 from the yeast Kluyveromyces lactis^[1].

A hexokinase is an enzyme that phosphorylates (adds phosphyryl groups) hexoses (six-carbon sugars). It takes in a substrate (usually glucose in most organisms) and adds a phosphate (usually from ATP) to form hexose phosphate as the product. When the substrate is glucose, the product is glucose-6-phosphate.
