Formed from S-adenosylmethionine after transmethylation reactions. Type Small Molecule Groups Experimental Structure S-adenosyl-l-homocysteine hydrolase from Pseudomonas aeruginosa (PaSAHase) coordinates one K+ ion and one Zn2+ ion in the substrate binding area. The cations affect the enzymatic activity and S-(5 -Adenosyl)-L-homocysteine (AdoHCys, SAH) is a competitive inhibitor (versus AdoMet) of DNA methyltransferases.

S- Adenosyl-L-methionine (AdoMet)-dependent methyltransferases (MTs) [E.C. 2.1.1-] catalyze the transfer of the methyl group of AdoMet to an acceptor molecule, with the concomitant formation of the corresponding methylated derivative and S -adenosyl-L-homocysteine (AdoHcy) as products. MTs are essential enzymes that play a variety of roles in the maintenance of biological activities of all organisms. Summary: The protein encoded by this gene is an enzyme that catalyzes the conversion of S-adenosyl-L-methionine (along with glycine) to S-adenosyl-L-homocysteine and sarcosine. The encoded protein is found in the cytoplasm and acts as a homotetramer. Defects in this gene are a cause of GNMT deficiency (hypermethioninemia). S-Adenosyl-l-homocysteine (SAH) is the biosynthetic precursor to homocysteine.

The method is based on enzymatic conversion of Hcy to S-adenosyl-L-homocysteine (SAH) by the action of SAH hydrolase (SAHase; EC 3.3.1.1), followed by quantification of SAH in a competitive immunoassay with use of a monoclonal anti-SAH antibody.

Stars This entity has been manually annotated by the ChEBI 2013-10-09 S-Adenosyl-L-homocysteine (SAH) is an amino acid derivative used in several metabolic pathways in most organisms. It is an intermediate in the synthesis of cysteine and adenosine. SAH is formed by the demethylation of S-adenosyl-L-methionine (SAM), which can … S-adenosyl-L-methionine and S-adenosyl-L-homocysteine, an NMR study Mark Stolowitz in the presence of a methyl group in the 5-position of the ring and its CP-MAS spectrum is essentially the same as that of uracil except for the appearance of methyl resonance at 115 ppm.
