[[http://www.uniprot.org/uniprot/ISCS_ECO57 ISCS_ECO57]] Catalyzes the removal of elemental sulfur and selenium atoms from cysteine and selenocysteine to produce alanine. Functions as a sulfur delivery protein for NAD, biotin and Fe-S cluster synthesis. Transfers sulfur on 'Cys-456' of ThiI in a transpersulfidation reaction. Functions also as a selenium delivery protein in the pathway for the biosynthesis of selenophosphate (By similarity). [[http://www.uniprot.org/uniprot/TUSA_ECO57 TUSA_ECO57]] Part of a sulfur-relay system required for 2-thiolation of 5-methylaminomethyl-2-thiouridine (mnm(5)s(2)U) at tRNA wobble positions. Interacts with IscS and stimulates its activity. Then, accepts a sulfur from IscS and transfers it in turn to TusD (Probable).<ref>PMID:20404999</ref>
