Protein

Microsomal glutathione S-transferase 1

Gene

Mgst1

Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

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

Catalytic activityi

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

Enzyme regulationi

Can be activated by reagents that attack Cys-50 sulfhydryl, such as N-ethylmaleimide, except in the testis. Activation also occurs via nitration of Tyr-93 by peroxynitrite.1 Publication
