Protein attributes

Sequence length	335 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Catalyzes the 2-beta-hydroxylation of several biologically active gibberellins, leading to the homeostatic regulation of their endogenous level. Catabolism of gibberellins (GAs) plays a central role in plant development. Converts GA9/GA20 to GA51/GA29 and GA4/GA1 to GA34/GA8.
Catalytic activity	Gibberellin 1 + 2-oxoglutarate + O(2) = 2-beta-hydroxygibberellin 1 + succinate + CO(2).
Cofactor	Iron By similarity.
Pathway	Plant hormone biosynthesis; gibberellin biosynthesis.
Sequence similarities	Belongs to the iron/ascorbate-dependent oxidoreductase family. GA2OX subfamily.
