Glutathione transferases (EC 2.5.1.18, GSTs) catalyze the nucleophilic attack of glutathione (GSH) on the electrophilic centre of a number of electrophilic compounds helping to detoxify a diverse array of toxic xenobiotics including carcinogenic, and pharmacologically active compounds. In this review, detailed descriptions are given on the structure and catalytic properties of human glutathione transferase P1-1 (hGSTP1-1) an enzyme that ubiquitously expressed in human tissues and exhibits many biological functions and multiple roles. The detoxification properties of hGSTP1-1 have been a primary research focus for the last years. However, now it has become apparent that the noncatalytic functions of GSTP1-1 have expanded the biological roles of this enzyme in cell survival, cell death and stress signalling mechanism.
