Summation

GPX2 (located in the gastrointestinal tract, also called GSHPx-GI, GPX-GI, and GI-GPx), like glutathione peroxidase 1 (GPX1, ubiquitous), reduces one molecule of hydrogen peroxide (H2O2) with two molecules of glutathione to yield one molecule of oxidized glutathione (glutathione disulfide, GSSG) and two molecules of water (Chu et al. 1998).
