Protein
Microsomal glutathione S-transferase 1
Gene
MGST1, GST12
Organism
Sus scrofa (Pig)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at transcript leveli

Functioni

Conjugation of reduced glutathione to a wide number of exogenous and endogenous hydrophobic electrophiles By similarity.

Catalytic activityi

RX + glutathione = HX + R-S-glutathione.

Enzyme regulationi

Can be activated by reagents that attack Cys-50 sulfhydryl, such as N-ethylmaleimide. Activation also occurs via nitration of Tyr-93 by peroxynitrite By similarity.
