| + | [[http://www.uniprot.org/uniprot/SAHH_HUMAN SAHH_HUMAN]] Adenosylhomocysteine is a competitive inhibitor of S-adenosyl-L-methionine-dependent methyl transferase reactions; therefore adenosylhomocysteinase may play a key role in the control of methylations via regulation of the intracellular concentration of adenosylhomocysteine.<ref>PMID:12590576</ref> | ||

| + | Optimization of a new series of S-adenosyl-L-homocysteine hydrolase (AdoHcyase) inhibitors based on non-adenosine analogs led to very potent compounds 14n, 18a, and 18b with IC50 values of 13 +/- 3, 5.0 +/- 2.0, and 8.5 +/- 3.1 nM, respectively. An X-ray crystal structure of AdoHcyase with NAD(+) and 18a showed a novel open form co-crystal structure. 18a in the co-crystals formed intramolecular eight membered ring hydrogen bond formations. A single crystal X-ray structure of 14n also showed an intramolecular eight-membered ring hydrogen bond interaction. | ||
