Enzyme Information

1.14.11.29

Hypoxia-inducible factor-proline dioxygenase.

based on mapping to UniProt Q9GZT9

Hypoxia-inducible factor-L-proline + 2-oxoglutarate + O(2) = hypoxia- inducible factor-trans-4-hydroxy-L-proline + succinate + CO(2).

-!- 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.
