Molybdenum cofactor sulfurase (MOCOS)

Sulfurates the molybdenum cofactor. Sulfation of molybdenum is vital 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.

In vitro, the C-terminal domain is able to reduce N-hydroxylated prodrugs, such as benzamidoxime. .
