ID   3.3.1.1
DE   Adenosylhomocysteinase.
AN   Adenosylhomocysteine hydrolase.
AN   AdoHcyase.
AN   S-adenosylhomocysteinase.
AN   S-adenosylhomocysteine hydrolase.
AN   S-adenosylhomocysteine synthase.
AN   SAHase.
CA   S-adenosyl-L-homocysteine + H(2)O = L-homocysteine + adenosine.
CF   NAD(+).
CC   -!- The NAD(+) cofactor appears to bring about a transient oxidation at
CC       C-3' of the 5'-deoxyadenosine residue, thus labilizing the thioether
CC       bond cf. EC 5.5.1.4.
