Names and origin

Protein names	Recommended name:     Glutathione S-transferase 3     EC=2.5.1.18 Alternative name(s):     GST-CL3     GST class-alpha
Organism	Gallus gallus (Chicken)
Taxonomic identifier	9031 [NCBI]
Taxonomic lineage	Eukaryota › Metazoa › Chordata › Craniata › Vertebrata › Euteleostomi › Archosauria › Dinosauria › Saurischia › Theropoda › Coelurosauria › Aves › Neognathae › Galliformes › Phasianidae › Phasianinae › Gallus

Protein attributes

Sequence length	229 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Catalyzes the conjugation of GSH to a wide variety of electrophilic alkylating agents. Also involved in the metabolism of lipid hydroperoxides, prostaglandins and leukotriene A4 and in binding of non-substrate hydrophobic ligands such as bile acids, a number of drugs and thyroid hormones. This GST does not exhibit peroxidase activity.
Catalytic activity	RX + glutathione = HX + R-S-glutathione.
Subunit structure	Homodimer or heterodimer (with a subunit from group CL-4).
Subcellular location	Cytoplasm.
Miscellaneous	The variations were found from AA sequencing and imply there are multiple forms of CL-3.
Sequence similarities	Belongs to the GST superfamily. Alpha family. Contains 1 GST C-terminal domain. Contains 1 GST N-terminal domain.
