Protein attributes

Sequence length	200 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Catalytic activity	L-cysteine + O(2) = 3-sulfinoalanine.
Cofactor	Binds 1 iron ion per subunit By similarity.
Pathway	Organosulfur biosynthesis; taurine biosynthesis; hypotaurine from L-cysteine: step 1/2.
Subunit structure	Monomer By similarity.
Post-translational modification	The thioether cross-link between Cys-93 and Tyr-157 plays a structural role through stabilizing the ferrous ion, and prevents the production of highly damaging free hydroxyl radicals by holding the oxygen radical via hydroxyl hydrogen By similarity.
Sequence similarities	Belongs to the cysteine dioxygenase family.
