S- (5′-Adenosyl)-L-homocys teine (AdoHcy/SAH) is a component of intracellular homocysteine stress. AdoHcy is a competitive inhibitor (versus AdoMet) of DNA methyltransferases (S-adenosyl-L-methionine (AdoMet)-dependent methyltransferases) involved in epigenetics.

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. S-Adenosyl-homocysteine (CAS number: 979-92-0) hydrolyzes in acid solution (0.1M HCl, 100°C, over 90 minutes) to form S-ribosylhomocysteine. It is not hydrolyzed in neutral alkaline solutions (stable in 0.1M NaOH at 25°C over 10 minutes), but oxidation is more rapid in alkaline solution. S-Adenosyl-homocysteine is slowly oxidized to the Abstract.

Varying amounts of S-(5′-adenosyl)-L-homocysteine were incubated with diﬀerent amounts of S-(5′-adenosyl)-L-homocysteine hydrolase in the presence of saturating concentration of L-methionine γ-lyase in citrate-phosphate buﬀer (25 mM, pH 6.4) for 20 min at 37 °C. For inhibition S-Adenosyl-l-homocysteine (SAH) is the biosynthetic precursor to homocysteine. SAH is formed by the demethylation of S-adenosyl-l-methionine. Adenosylhomocysteinase converts SAH into homocysteine and adenosine.

Lowe GDO. Circulating inflammatory S-adenosylmethionine. S-adenosylhomocysteine homocysteine.

A sensitive method has been developed for the simultaneous determination of S‐adenosyl‐L‐homocysteine (SAH) and S‐adenosyl‐L‐methionine (SAM) in a variety of plant tissues.

2012-04-04 In addition to its unusual mRNA capping and methyltransferase mechanisms, the addition of S-adenosyl homocysteine (SAH), which is the by-product and competitive inhibitor of S-adenosyl methionine (SAM)-mediated methyltransferase reactions, leads to synthesis of poly (A) tails on the 3' end of VSV mRNAs that are 10- or 20-fold longer than normal.

Se hela listan på frontiersin.org Here we report that Myc promotes upregulation of S-adenosyl homocysteine hydrolase (SAHH), an enzyme which hydrolyzes S-adenosyl homocysteine, thus neutralizing its inhibitory effects, and this is required for c-Myc-induced mRNA cap methylation.
