Adenosylhomocysteinase (AHCY) is an enzyme that catalyzes the reversible hydrolysis of S-adenosylhomocysteine (SAH) to adenosine (Ado) and L-homocysteine (Hcy). It regulates the intracellular SAH concentration thought to be important for transmethylation reactions. Deficiency in this protein is one of the different causes of hypermethioninemia. Recombinant human AHCY protein, fused to His-tag at N-terminus, was expressed in E. coli, and purified by using proprietary chromatography techniques. This enzyme is validated for AHCY activity application.
