Names and origin

Protein names	Recommended name:     Glutathione S-transferase class-mu 28 kDa isozyme       Short name=GST 28     EC=2.5.1.18 Alternative name(s):     Sb28GST
Organism	Schistosoma bovis (Blood fluke)
Taxonomic identifier	6184 [NCBI]
Taxonomic lineage	Eukaryota › Metazoa › Platyhelminthes › Trematoda › Digenea › Strigeidida › Schistosomatoidea › Schistosomatidae › Schistosoma

Protein attributes

Sequence length	211 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Conjugation of reduced glutathione to a wide number of exogenous and endogenous hydrophobic electrophiles. GST isoenzymes appear to play a central role in the parasite detoxification system. Other functions are also suspected including a role in increasing the solubility of haematin in the parasite gut.
Catalytic activity	RX + glutathione = HX + R-S-glutathione.
Subunit structure	Homodimer.
Sequence similarities	Belongs to the GST superfamily. Mu family. Contains 1 GST C-terminal domain. Contains 1 GST N-terminal domain.
