CC -!- FUNCTION: May play a key role in the regulation of the intracellular
CC concentration of adenosylhomocysteine. {ECO:0000255|HAMAP-
CC Rule:MF_00563}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + S-adenosyl-L-homocysteine = adenosine + L-homocysteine;
CC Xref=Rhea:RHEA:21708, ChEBI:CHEBI:15377, ChEBI:CHEBI:16335,
CC ChEBI:CHEBI:57856, ChEBI:CHEBI:58199; EC=3.3.1.1;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00563};
CC -!- COFACTOR:
CC Name=NAD(+); Xref=ChEBI:CHEBI:57540;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00563};
CC Note=Binds 1 NAD(+) per subunit. {ECO:0000255|HAMAP-Rule:MF_00563};
CC -!- PATHWAY: Amino-acid biosynthesis; L-homocysteine biosynthesis; L-
CC homocysteine from S-adenosyl-L-homocysteine: step 1/1.
CC {ECO:0000255|HAMAP-Rule:MF_00563}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00563}.
CC -!- SIMILARITY: Belongs to the adenosylhomocysteinase family.
CC {ECO:0000255|HAMAP-Rule:MF_00563}.
