Function

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 and selenium atoms from cysteine and selenocysteine to produce alanine. Functions as a sulfur delivery protein for Fe-S cluster synthesis onto IscU, an Fe-S scaffold assembly protein, as well as other S acceptor proteins.

Biological Context

Subcellular Location: Cytoplasm
Pathway: Cofactor biosynthesis; iron-sulfur cluster biosynthesis

Product Specifications
