CC -!- FUNCTION: Cysteine desulfurases mobilize the sulfur from L-cysteine to
CC yield L-alanine, an essential step in sulfur metabolism for
CC biosynthesis of a variety of sulfur-containing biomolecules. Component
CC of the suf operon, which is activated and required under specific
CC conditions such as oxidative stress and iron limitation. Acts as a
CC potent selenocysteine lyase in vitro, that mobilizes selenium from L-
CC selenocysteine. Selenocysteine lyase activity is however unsure in
CC vivo. {ECO:0000255|HAMAP-Rule:MF_01831}.
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_01831};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=AH2 + L-selenocysteine = A + H(+) + hydrogenselenide + L-
CC alanine; Xref=Rhea:RHEA:11632, ChEBI:CHEBI:13193, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:17499, ChEBI:CHEBI:29317, ChEBI:CHEBI:57843,
CC ChEBI:CHEBI:57972; EC=4.4.1.16; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01831};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01831};
CC -!- PATHWAY: Cofactor biosynthesis; iron-sulfur cluster biosynthesis.
CC {ECO:0000255|HAMAP-Rule:MF_01831}.
CC -!- SUBUNIT: Homodimer. Interacts with SufE and the SufBCD complex composed
CC of SufB, SufC and SufD. The interaction with SufE is required to
CC mediate the direct transfer of the sulfur atom from the S-
CC sulfanylcysteine. {ECO:0000255|HAMAP-Rule:MF_01831}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01831}.
CC -!- SIMILARITY: Belongs to the class-V pyridoxal-phosphate-dependent
CC aminotransferase family. Csd subfamily. {ECO:0000255|HAMAP-
CC Rule:MF_01831}.
