Superclasses: Reactions Classified By Conversion Type Simple Reactions Chemical Reactions Protein-Modification Reactions
Reactions Classified By Substrate Macromolecule Reactions Protein-Reactions Protein-Modification Reactions

EC Number: 1.14.11.30

Enzymes and Genes:
hypoxia-inducible factor-asparagine dioxygenase Inferred from experiment : HIF1AN ( Homo sapiens )

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.

Mass balance status: Undetermined; a substrate lacks a chemical formula

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

Enzyme Commission Synonyms: HIF hydroxylase

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.
