Protein attributes

Sequence length	338 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Catalyzes the 2-beta-hydroxylation of gibberellins (GA) precursors, rendering them unable to be converted to active GAs. Hydroxylates the C20-GA GA12 and GA53, but is not active on C19-GAs, like GA1, GA4, GA9 and GA20. Ref.3
Catalytic activity	Gibberellin 1 + 2-oxoglutarate + O2 = 2-beta-hydroxygibberellin 1 + succinate + CO2.
Cofactor	Iron By similarity.
Pathway	Plant hormone biosynthesis; gibberellin biosynthesis.
Sequence similarities	Belongs to the iron/ascorbate-dependent oxidoreductase family. GA2OX subfamily. Contains 1 Fe2OG dioxygenase domain.
Sequence caution	The sequence ABK28642.1 differs from that shown. Reason: Erroneous termination at position 339. Translated as stop. The sequence CAA17539.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAB79120.1 differs from that shown. Reason: Erroneous gene model prediction.
