P79382

- MGST1_PIG

UniProt

P79382 - MGST1_PIG

Protein

Microsomal glutathione S-transferase 1

Gene

MGST1

Organism
Sus scrofa (Pig)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at transcript leveli
  1. 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.By similarity
