Disease
MOC2A_HUMAN Sulfite oxidase deficiency due to molybdenum cofactor deficiency type B. The disease is caused by mutations affecting the gene represented in this entry.
Function
MOC2A_HUMAN 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.[HAMAP-Rule:MF_03051][1]
