CC -!- FUNCTION: Master enzyme that delivers sulfur to a number of partners
CC involved in Fe-S cluster assembly, tRNA modification or cofactor
CC biosynthesis. Catalyzes the removal of elemental sulfur atoms from
CC cysteine to produce alanine. Functions as a sulfur delivery protein for
CC Fe-S cluster synthesis onto IscU, an Fe-S scaffold assembly protein, as
CC well as other S acceptor proteins. {ECO:0000255|HAMAP-Rule:MF_00331}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[sulfur carrier]-H + L-cysteine = [sulfur carrier]-SH + L-
CC alanine; Xref=Rhea:RHEA:43892, Rhea:RHEA-COMP:14737, Rhea:RHEA-
CC COMP:14739, ChEBI:CHEBI:29917, ChEBI:CHEBI:35235, ChEBI:CHEBI:57972,
CC ChEBI:CHEBI:64428; EC=2.8.1.7; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_00331};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00331};
CC -!- PATHWAY: Cofactor biosynthesis; iron-sulfur cluster biosynthesis.
CC {ECO:0000255|HAMAP-Rule:MF_00331}.
CC -!- SUBUNIT: Homodimer. Forms a heterotetramer with IscU, interacts with
CC other sulfur acceptors. {ECO:0000255|HAMAP-Rule:MF_00331}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00331}.
CC -!- SIMILARITY: Belongs to the class-V pyridoxal-phosphate-dependent
CC aminotransferase family. NifS/IscS subfamily. {ECO:0000255|HAMAP-
CC Rule:MF_00331}.
