Comments [?]

FUNCTIONSulfurates the molybdenum cofactor. Sulfation of molybdenum is essential for xanthine dehydrogenase (XDH) and aldehyde oxidase (ADO) enzymes in which molybdenum cofactor is liganded by 1 oxygen and 1 sulfur atom in active form.
CATALYTIC ACTIVITY Reaction=AH2 + L-cysteine + Mo-molybdopterin = A + H2O + L-alanine + thio-Mo-molybdopterin; Xref=Rhea:RHEA:42636, ChEBI:CHEBI:13193, ChEBI:CHEBI:15377, ChEBI:CHEBI:17499, ChEBI:CHEBI:35235, ChEBI:CHEBI:57972, ChEBI:CHEBI:71302, ChEBI:CHEBI:82685; EC=2.8.1.9;
COFACTOR Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
SIMILARITYBelongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. MOCOS subfamily.
