Glycerol kinase

Gene

Gk

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Key enzyme in the regulation of glycerol uptake and metabolism.By similarity

Catalytic activityi

ATP + glycerol = ADP + sn-glycerol 3-phosphate.

Pathwayi: glycerol degradation via glycerol kinase pathway

This protein is involved in step 1 of the subpathway that synthesizes sn-glycerol 3-phosphate from glycerol.
Proteins known to be involved in this subpathway in this organism are:
  1. Glycerol kinase 2 (Gk2), Glycerol kinase (Gk), Putative glycerol kinase 5 (Gk5)
This subpathway is part of the pathway glycerol degradation via glycerol kinase pathway, which is itself part of Polyol metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes sn-glycerol 3-phosphate from glycerol, the pathway glycerol degradation via glycerol kinase pathway and in Polyol metabolism.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
