Protein
Molybdopterin synthase sulfur carrier subunit
Organism
Emericella nidulans (strain FGSC A4 / ATCC 38163 / CBS 112.46 / NRRL 194 / M139)
Function
Acts as a sulfur carrier required for molybdopterin biosynthesis. Component of the molybdopterin synthase complex that catalyzes the conversion of precursor Z into molybdopterin by mediating the incorporation of 2 sulfur atoms into precursor Z to generate a dithiolene group. In the complex, serves as sulfur donor by being thiocarboxylated (-COSH) at its C-terminus by uba4. After interaction with MOCS2B, the sulfur is then transferred to precursor Z to form molybdopterin.
Similarity
Belongs to the MoaD family. MOCS2A subfamily.
