Factor Inhibiting HIF-1 Alpha D201A Mutant in Complex with FE(II), Alpha-Ketoglutarate and HIF-1 Alpha 35mer


Function and Biology Details

Reactions catalysed:
[Ankyrin-repeat domain protein]-L-asparagine + 2-oxoglutarate + O(2) = [ankyrin-repeat domain protein]-(3S)-3-hydroxy-L-asparagine + succinate + CO(2) 
Hypoxia-inducible factor-L-asparagine + 2-oxoglutarate + O(2) = hypoxia-inducible factor-(3S)-3-hydroxy-L-asparagine + succinate + CO(2)
