Protein

Guanidinoacetate N-methyltransferase

Gene

GAMT

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Converts guanidinoacetate to creatine, using S-adenosylmethionine as the methyl donor (PubMed:26003046, PubMed:24415674, PubMed:26319512). Important in nervous system development (PubMed:24415674).3 Publications

Catalytic activityi

S-adenosyl-L-methionine + guanidinoacetate = S-adenosyl-L-homocysteine + creatine.PROSITE-ProRule annotation

Pathwayi: creatine biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes creatine from L-arginine and glycine.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Glycine amidinotransferase, mitochondrial (GATM)
  2. Guanidinoacetate N-methyltransferase (GAMT)
This subpathway is part of the pathway creatine biosynthesis, which is itself part of Amine and polyamine biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes creatine from L-arginine and glycine, the pathway creatine biosynthesis and in Amine and polyamine biosynthesis.

Pathology & Biotechi

Involvement in diseasei

Cerebral creatine deficiency syndrome 2 (CCDS2)11 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionAn autosomal recessive disorder characterized by developmental delay and regression, mental retardation, severe disturbance of expressive and cognitive speech, intractable seizures, movement disturbances, severe depletion of creatine and phosphocreatine in the brain, and accumulation of guanidinoacetic acid in brain and body fluids.
