CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:21709;
CC Evidence={ECO:0000250|UniProtKB:P10760};
CC -!- COFACTOR:
CC Name=NAD(+); Xref=ChEBI:CHEBI:57540;
CC Evidence={ECO:0000250|UniProtKB:P10760};
CC Note=Binds 1 NAD(+) per subunit. {ECO:0000250|UniProtKB:P10760};
CC -!- PATHWAY: Amino-acid biosynthesis; L-homocysteine biosynthesis; L-
CC homocysteine from S-adenosyl-L-homocysteine: step 1/1.
CC -!- SUBUNIT: Homotetramer. Interaction with AHCYL1 (By similarity).
CC {ECO:0000250|UniProtKB:P10760, ECO:0000250|UniProtKB:P23526}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P23526}.
CC Melanosome {ECO:0000250|UniProtKB:P23526}. Nucleus
