What is "adenosylhomocysteinase"

Adenosylhomocysteinase (, S-adenosylhomocysteine synthase, S-adenosylhomocysteine hydrolase, adenosylhomocysteine hydrolase, S-adenosylhomocysteinase, SAHase, AdoHcyase) is an enzyme that converts S-adenosylhomocysteine to homocysteine and adenosine. This enzyme catalyses the following chemical reaction

S-adenosyl-L-homocysteine + HO $\rightleftharpoons$ L- homocysteine + adenosine

The enzyme contains one tightly bound NAD per subunit.
