Description
Guanidinoacetate N-methyltransferase isoform a, also known as GAMT is a methyltansferase that converts guanidoacetate to creatine, using S-adenosylmethionine as the methyl domor. This enzyme participates in the two-step synthesis of the compound creatine from the protein building blocks glycine, arginine, and methionine. It is involved in providing energy for muscle contraction, and is also important in nervous system functioning. Also GAMT is active in the liver, pancreas, and kidneys. Recombinant human GAMT, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques
