Summary
Description
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.
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 MOCS3. After interaction with MOCS2B, the sulfur is then transferred to precursor Z to form molybdopterin.
Catalytic Activity
2 [molybdopterin-synthase sulfur-carrier protein]-C-terminal Gly-NH-CH2-C(O)SH + cyclic pyranopterin phosphate + H2O = 2 [molybdopterin-synthase sulfur-carrier protein]-C-terminal Gly-Gly + 4 H(+) + molybdopterin
Subunit
Heterotetramer; composed of 2 small (MOCS2A) and 2 large (MOCS2B) subunits.
Miscellaneous
This protein is produced by a bicistronic gene which also produces the large subunit (MOCS2A).
This protein is produced by a bicistronic gene which also produces the large subunit (MOCS2B).
Similarity
Belongs to the MoaE family. MOCS2B subfamily.
Belongs to the MoaD family. MOCS2A subfamily.
