Function
Glutathione S-transferase (GST) catalyzes the conjugation of reduced glutathione (GSH) to a variety of exogenous and endogenous hydrophobic electrophiles. For example, GST can detoxify peroxidised lipids. All eukaryotes possess a variety of GSTs with catalytic and non-catalytic activities. GST is divided into classes: α, δ, ε, κ, μ, ν, ω, π, ρ, σ (hematopoietic prostaglandin D synthase), τ, χ, ϑ, ζ and microsomal[1].
- epsilon glutathione S-transferase has a role in insecticide resistance[2].
- kappa glutathione S-transferase is found in mitochondria and peroxisomes. It may be involved in lipid metabolism[3].
- mu glutathione S-transferase detoxify carcinogens in tobacco smoke[4].
- nu glutathione S-transferase breaks the beta-aryl ether bond of lignin[5].
- pi glutathione S-transferase has a orle in carcinogenic processes[6].
Relevance
GST are targets for anti-diabetic drugs.
