HUMAN GLUTATHIONE TRANSFERASE A4-4 WITHOUT LIGANDS
Overview
The oxidation of lipids and cell membranes generates cytotoxic compounds, implicated in the etiology of aging, cancer, atherosclerosis, neurodegenerative diseases, and other illnesses. Glutathione transferase, (GST) A4-4 is a key component in the defense against the products of this, oxidative stress because, unlike other Alpha class GSTs, GST A4-4 shows, high catalytic activity with lipid peroxidation products such as, 4-hydroxynon-2-enal (HNE). The crystal structure of human apo GST A4-4, unexpectedly possesses an ordered C-terminal alpha-helix, despite the, absence of any ligand. The structure of human GST A4-4 in complex with the, inhibitor S-(2-iodobenzyl) glutathione reveals key features of the, electrophilic substrate-binding pocket which confer specificity toward, HNE.
