In brief, the first and rate-limiting step is the abstraction of a hydrogen atom by non-heme ferric iron (Fe(III)), involving a proton-coupled electron transfer in which the electron is transferred directly to the iron and the proton is acquired simultaneously by the hydroxide ligand in a concerted mechanism to give a substrate radical, while the iron atom is reduced to the ferrous state (Fe(II))

As per recent studies, the translation of the mRNAs of seleno-GPxs having low priority for selenium utilization (like GPx1) is not favored under low intracellular selenium status due to the interaction of a selenium responsive negative regulator such as eukaryotic initiation factor 4a3 (eIF4a3) with their 3-UTR (Fig
