- Gibberellin-44 dioxygenase
In
enzymology , a gibberellin-44 dioxygenase (EC number|1.14.11.12) is anenzyme that catalyzes thechemical reaction :gibberellin 44 + 2-oxoglutarate + O2 gibberellin 19 + succinate + CO2
The 3 substrates of this enzyme are
gibberellin 44 ,2-oxoglutarate , and O2, whereas its 3 products aregibberellin 19 ,succinate , and CO2.This enzyme belongs to the family of
oxidoreductase s, specifically those acting on paired donors, with O2 as oxidant and incorporation or reduction of oxygen. The oxygen incorporated need not be derived from O2 with 2-oxoglutarate as one donor, and incorporation of one atom o oxygen into each donor. The systematic name of this enzyme class is (gibberellin-44),2-oxoglutarate:oxygen oxidoreductase. Other names in common use include oxygenase, gibberellin A44 oxidase, and (gibberellin-44), 2-oxoglutarate:oxygen oxidoreductase. This enzyme participates inditerpenoid biosynthesis . It employs one cofactor,iron .References
