Ankyrin-repeat-histidine dioxagenase.

based on mapping to UniProt Q9NWT6

(1) [Ankyrin-repeat domain protein]-L-histidine + 2-oxoglutarate + O(2) = [ankyrin-repeat domain protein]-(3S)-3-hydroxy-L-histidine + succinate + CO(2). (2) [Ankyrin-repeat domain protein]-L-asparagine + 2-oxoglutarate + O(2) = [ankyrin-repeat domain protein]-(3S)-3-hydroxy-L-asparagine + succinate + CO(2). (3) [Ankyrin-repeat domain protein]-L-aspartate + 2-oxoglutarate + O(2) = [ankyrin-repeat domain protein]-(3S)-3-hydroxy-L-aspartate + succinate + CO(2).

1.14.11.30

Hypoxia-inducible factor-asparagine dioxygenase.

based on mapping to UniProt Q9NWT6

Hypoxia-inducible factor-L-asparagine + 2-oxoglutarate + O(2) = hypoxia- inducible factor-(3S)-3-hydroxy-L-asparagine + succinate + CO(2).

-!- Contains iron, and requires ascorbate. -!- Catalyzes hydroxylation of an asparagine in the C-terminal transcriptional activation domain of HIF-alpha, the alpha subunit of the transcriptional regulator HIF (hypoxia-inducible factor), which reduces its interaction with the transcriptional coactivator protein p300. -!- The requirement of oxygen for the hydroxylation reaction enables animals to respond to hypoxia.
