Enzyme Information
| 3.3.1.1 |
Adenosylhomocysteinase.
based on mapping to UniProt P10760
S-adenosyl-L-homocysteine + H(2)O = L-homocysteine + adenosine.
-!- The NAD(+) cofactor appears to bring about a transient oxidation at C-3' of the 5'-deoxyadenosine residue, thus labilizing the thioether bond cf. EC 5.5.1.4.
