CC   -!- FUNCTION: Catalyzes the oxidation of cysteine to cysteine sulfinic acid
CC       with addition of molecular dioxygen. {ECO:0000250|UniProtKB:Q16878}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=L-cysteine + O2 = 3-sulfino-L-alanine + H(+);
CC         Xref=Rhea:RHEA:20441, ChEBI:CHEBI:15378, ChEBI:CHEBI:15379,
CC         ChEBI:CHEBI:35235, ChEBI:CHEBI:61085; EC=1.13.11.20;

CC         Evidence={ECO:0000250|UniProtKB:Q16878};
CC   -!- COFACTOR:
CC       Name=Fe cation; Xref=ChEBI:CHEBI:24875;
CC         Evidence={ECO:0000250|UniProtKB:P60334};
CC       Name=Ni(2+); Xref=ChEBI:CHEBI:49786;
CC         Evidence={ECO:0000250|UniProtKB:P60334};
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC         Evidence={ECO:0000250|UniProtKB:P60334};
CC       Note=Binds 1 Fe cation per subunit. Ni(2+) and Zn(2+) can be used to a
CC       lesser extent. {ECO:0000250|UniProtKB:P60334};
CC   -!- PATHWAY: Organosulfur biosynthesis; taurine biosynthesis; hypotaurine
CC       from L-cysteine: step 1/2.
CC   -!- SUBUNIT: Monomer. {ECO:0000250|UniProtKB:Q16878}.
CC   -!- PTM: The thioether cross-link between Cys-93 and Tyr-157 plays a
CC       structural role through stabilizing the Fe(2+) ion, and prevents the
CC       production of highly damaging free hydroxyl radicals by holding the
CC       oxygen radical via hydroxyl hydrogen. {ECO:0000250|UniProtKB:Q16878}.
CC   -!- SIMILARITY: Belongs to the cysteine dioxygenase family. {ECO:0000305}.
