S-adenosylhomocysteine hydrolase

Function S-adenosylhomocysteine hydrolase (AHCH) converts S-adenosylhomocysteine (AdoHcy) to L-homocysteine and adenosine. AHCH uses NAD+ as cofactor. AHCH is an essential enzyme in processes like transmethylation, trans-sulfuration and purine metabolism. Disease AHCH deficiency causes a genetic disorder of methionine metabolism. Structural highlights The biological assembly of rat S-adenosylhomocysteine hydrolase is . AHCH structure contains . The .
