General annotation (Comments)

Function

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

Catalytic activity

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

Enzyme regulation

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.

Subunit structure

Homotrimer; The trimer binds only one molecule of glutathione By similarity.

Subcellular location

Microsome By similarity. Mitochondrion outer membrane; Peripheral membrane protein By similarity. Endoplasmic reticulum membrane; Multi-pass membrane protein By similarity.

Post-translational modification

Peroxynitrite induces nitration at Tyr-93 which activates the enzyme By similarity.

Sequence similarities

Belongs to the MAPEG family.
