CC -!- FUNCTION: Adenosylhomocysteine is a competitive inhibitor of S-
CC adenosyl-L-methionine-dependent methyl transferase reactions; therefore
CC adenosylhomocysteinase may play a key role in the control of
CC methylations via regulation of the intracellular concentration of
CC adenosylhomocysteine. {ECO:0000250}.
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 -!- COFACTOR:
CC Name=NAD(+); Xref=ChEBI:CHEBI:57540; Evidence={ECO:0000250};
CC Note=Binds 1 NAD(+) per subunit. {ECO:0000250};
CC -!- PATHWAY: Amino-acid biosynthesis; L-homocysteine biosynthesis; L-
CC homocysteine from S-adenosyl-L-homocysteine: step 1/1.
CC -!- SUBUNIT: Homotetramer. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the adenosylhomocysteinase family.
CC {ECO:0000305}.
