Plasma s-adenosylmethionine (SAM), s-adenosylhomocysteine (SAH), homocysteine (Hcy) and vitamin B12 was included as one-carbon metabolism markers.

S-adenosylhomocysteine (SAH) is known to be a potent inhibitor of S- adenosylmethionine (SAM)-mediated reactions, of which SAH itself is a product. Homocystinuria caused by cystathionine beta-synthase (CBS) deficiency is also called classical homocystinuria. CBS is an enzyme.

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.

Here we investigated inhibition of the flavivirus MTase by several AdoHcy-derivatives. Unexpectedly we found that S-adenosyl-L-homocysteine (AdoHcy) is metabolized in most species through a single pathway by the enzyme AdoHcy hydrolase (adenosylhomocysteinase; EC 3.3.1.1), which catalyzes the reversible hydrolysis of AdoHcy to adenosine and L-homocysteine (1). AdoHcy is one of the productsofmethyl-transferreactionsfromS-adenosylmethi- Se hela listan på hindawi.com Applications of S-Adenosyl-Homocysteine antibody This product has been reported to work in the following applications.

However, how cellular metabolism directs circadian chromatin remodeling is virtually unexplored. We report that the S-adenosylhomocysteine (SAH) hydrolyzing enzyme adenosylhomocysteinase (AHCY) cyclically associates to CLOCK-BMAL1 at chromatin sites and promotes circadian transcriptional activity.

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. SAH is formed by the demethylation of S -adenosyl- l -methionine .
