The direction shown, i.e. which substrates are on the left and right sides, is in accordance with the direction in which it was curated.

Mass balance status: Balance undetermined; a substrate lacks a chemical formula

Enzyme Commission Primary Name: hypoxia-inducible factor-asparagine dioxygenase

Enzyme Commission Synonyms: HIF hydroxylase

Taxonomic Range: Metazoa

Enzyme Commission Summary:
Contains iron, and requires ascorbate. Catalyses hydroxylation of an asparagine in the C-terminal transcriptional activation domain of HIF-α, the α 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.
