Prolyl hydroxylase domain (PHD) proteins mediate oxygen-dependent degradation of Hypoxia-inducible factor (HIF) α subunit. They include PHD1, PHD2 and PHD3. The PHD is a Fe+2/oxogluterate (2OG)-dependent enzyme. 3ouh is the crystallized structure of the enzyme PHD2, an oxidoreductase that is 237 amino acids long with a molecular weight of 27 kDa. 3ouh is found in Homo sapiens and is a homolog of EGLN1 found in C. elegans. The protein has three ligands: , , and SO4 (a sulfate ion). Water molecules shown as red spheres. It is involved in mediating physiological responses to hypoxia by degrading the transcription factor of a hypoxia-inducible factor HIF1-α. In hypoxic conditions, the activity of PHD2 lessens, causing an increase in HIF1-α, resulting in secretion of erythropoietin, anaerobic glycolysis, and angiogenesis[1].
