Description
Master enzyme that delivers sulfur to a number of partners involved in Fe-S cluster assembly, tRNA modification or cofactor biosynthesis. Catalyzes the removal of elemental sulfur from cysteine to produce alanine via an enzyme-bound persulfide intermediate. Functions as a sulfur delivery protein for Fe-S cluster synthesis. Cluster assembly on IscU homodimers proceeds sequentially from 1 2Fe-2S per dimer, to 2 2Fe-2S per dimer and finally 1 4Fe-4S per dimer.
Family
Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. NifS/IscS subfamily.
