Contains iron, and requires ascorbate. Specifically hydroxylates a proline residue in HIF-alpha, the alpha subunit of the transcriptional regulator HIF (hypoxia-inducible factor), which targets HIF for proteasomal destruction. The requirement of oxygen for the hydroxylation reaction enables animals to respond to hypoxia.
