>cd03188 GST_C_Beta GST_C family, Class Beta subfamily; GSTs are cytosolic dimeric proteins involved in cellular detoxification by catalyzing the conjugation of glutathione (GSH) with a wide range of endogenous and xenobiotic alkylating agents, including carcinogens, therapeutic drugs, environmental toxins, and products of oxidative stress. The GST fold contains an N-terminal thioredoxin-fold domain and a C-terminal alpha helical domain, with an active site located in a cleft between the two domains. GSH binds to the N-terminal domain while the hydrophobic substrate occupies a pocket in the C-terminal domain. Unlike mammalian GSTs which detoxify a broad range of compounds, the bacterial class Beta GSTs exhibit limited GSH conjugating activity with a narrow range of substrates. In addition to GSH conjugation, they also bind antibiotics and reduce the antimicrobial activity of beta-lactam drugs. The structure of the Proteus mirabilis enzyme reveals that the cysteine in the active site for
