Glycerol kinase, encoded by the gene GK, is a phosphotransferase enzyme involved in triglycerides and glycerophospholipids synthesis.

This glycerol is instead shuttled to the liver via the blood where it is: This protein may use the morpheein model of allosteric regulation.

[1] Glycerol Kinase (alternative name, ATP:glycerol 3-phosphotransferase or Glycerokinase) adopts a ribonuclease H-like fold consisting of an alpha-beta 2-layer sandwich of CATH family 3.30.420.40.

As of March 2010[update], there were 20 structures of this protein in the PDB, most of which are homodimeric.
