At4g10100

Gene
At4g10100
Protein
Molybdopterin synthase sulfur carrier subunit
Organism
Arabidopsis thaliana
Length
96 amino acids
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 MOCS3. After interaction with MOCS2B, the sulfur is then transferred to precursor Z to form molybdopterin.
Similarity
Belongs to the MoaD family. MOCS2A subfamily.
Mass
