Protein attributes

Sequence length	190 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Catalytic activity	L-cysteine + O2 = 3-sulfinoalanine.
Cofactor	Binds 1 iron ion per subunit By similarity.
Pathway	Organosulfur biosynthesis; taurine biosynthesis; hypotaurine from L-cysteine: step 1/2.
Post-translational modification	The thioether cross-link between Cys-85 and Tyr-149 plays a structural role through stabilizing the Fe2+ 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.
