Glutathione S-transferase

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].

Relevance

GST are targets for anti-diabetic drugs.

Structural highlights

The glutathione binding site is at the N-terminal of GST^[2].
