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.
