2015-11-17 · S-adenosyl-L-homocysteine hydrolase (SAH hydrolase or SAHH) is a highly conserved enzyme that catalyses the reversible hydrolysis of SAH to L-homocysteine (HCY) and adenosine (ADO). High

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 …

ATP. Methionine synthase. Methylation. Eg DNA, proteins, phospholipids. Folsyra är en syntetisk form av folat, ännu en viktigt. Adenosin kan också genereras från hydrolysen av S-adenosyl-homocystein (SAH). Som svar på hög metabolisk aktivitet extruderas ATP och adenosin till utsidan Förhöjd nivå av homocystein ses vid brist på folat och/eller kobalaminer.

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).

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. 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.

SAHase activity is also a significant source of l-homocysteine and adenosine, two compounds involved in numerous vital, as well as pathological processes.

5'-S-(3-Amino-3-carboxypropyl)-5'-thioadenosine. 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.
