Crystal Structure of Human Glycine N-Methyltransferase
Template:ABSTRACT PUBMED 15340920
Disease
[GNMT_HUMAN] Defects in GNMT are the cause of glycine N-methyltransferase deficiency (GNMT deficiency) [MIM:606664]; also known as hypermethioninemia. The only clinical abnormalities in patients with this deficiency are mild hepatomegaly and chronic elevation of serum transaminases.
Function
[GNMT_HUMAN] Catalyzes the methylation of glycine by using S-adenosylmethionine (AdoMet) to form N-methylglycine (sarcosine) with the concomitant production of S-adenosylhomocysteine (AdoHcy). Possible crucial role in the regulation of tissue concentration of AdoMet and of metabolism of methionine.[1][2]
About this Structure
