Glycerokinase is a phosphotransferase agitator complex in triglycerides and glycerophospholipids synthesis.
Glycerol kinase catalyzes the alteration of a phosphate from ATP to glycerol appropriately basic glycerol phosphate (ATP + glycerol <=> ADP + sn-glycerol 3-phosphate). Adipocytes abridgement glycerol kinase so they cannot metabolize the glycerol produced during triacyl glycerol degradation.
This protein may use the morpheein archetypal of allosteric regulation.
Structure
Glycerokinase (alternative name, ATP:glycerol 3-phosphotransferase or Glycerokinase) adopts a ribonuclease H-like bend consisting of an alpha-beta 2-layer sandwich of CATH ancestors 3.30.420.40. As of March 2010, there were 20 structures of this protein in the PDB, a lot of of which are homodimeric.
Glycerol kinase is a bacterial sugar kinase which catalyzes the Mg-ATP-dependent phosphorylation of glycerol to yield glycerol 3-phosphate. The enzyme from Escherichia coli is an allosteric regulatory enzyme whose activity is inhibited by fructose 1,6-bisphosphate (FBP) and the glucose-specific phosphocarrier of the phosphoenolpyruvate:glycose phosphotransferase system, IIA(Glc), structural studies suggest a nucleophilic in-line transfer mechanism for the ATP-dependent phosphorylation of glycerol by glycerol kinase.
