General annotation (Comments)

Catalytic activity

ATP + D-hexose = ADP + D-hexose 6-phosphate.

Enzyme regulation

Hexokinase is an allosteric enzyme inhibited by its product Glc-6-P By similarity.

Pathway

Carbohydrate metabolism; hexose metabolism.

Subunit structure

Monomer By similarity.

Domain

The N- and C-terminal halves of this hexokinase show extensive sequence similarity to each other. The catalytic activity is associated with the C-terminus while regulatory function is associated with the N-terminus.

Miscellaneous

In vertebrates there are four major glucose-phosphorylating isoenzymes, designated hexokinase I, II, III and IV (glucokinase).

Sequence similarities

Belongs to the hexokinase family.
