BRITE hierarchy
Sysname
hypoxia-inducible factor-L-asparagine, 2-oxoglutarate:oxygen oxidoreductase (4-hydroxylating)
Reaction(IUBMB)
hypoxia-inducible factor-L-asparagine + 2-oxoglutarate + O2 = hypoxia-inducible factor-(3S)-3-hydroxy-L-asparagine + succinate + CO2
Substrate
hypoxia-inducible factor-L-asparagine;
2-oxoglutarate [CPD:
C00026 ];
O2 [CPD:
C00007 ]
Product
hypoxia-inducible factor-(3S)-3-hydroxy-L-asparagine;
succinate [CPD:
C00042 ];
CO2 [CPD:
C00011 ]
Comment
Contains iron, and requires ascorbate. Catalyses 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.
