B0X1V5 · MOC2B_CULQU

Function

function

Catalytic subunit of the molybdopterin synthase complex, a complex that catalyzes the conversion of precursor Z into molybdopterin. Acts by mediating the incorporation of 2 sulfur atoms from thiocarboxylated MOCS2A into precursor Z to generate a dithiolene group.

Miscellaneous

This protein is produced by a bicistronic gene which also produces the large subunit (MOCS2A).

Catalytic activity

Pathway

Cofactor biosynthesis; molybdopterin biosynthesis.
