Adenosylhomocysteinase (EC 3.3.1.1, S-adenosylhomocysteine synthase, S-adenosylhomocysteine hydrolase, adenosylhomocysteine hydrolase, S-adenosylhomocysteinase, SAHase, AdoHcyase) is an enzyme that converts S-adenosylhomocysteine to homocysteine and adenosine.[1][2] This enzyme catalyses the following chemical reaction
- S-adenosyl-L-homocysteine + H2O ⇌ L-homocysteine + adenosine
The enzyme contains one tightly bound NAD+ per subunit.
