Protein

Gibberellin 3-beta-dioxygenase 1

Gene

LE

Organism
Pisum sativum (Garden pea)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Converts the inactive gibbberellin (GA) precursors GA9 and GA20 in the bioactives gibberellins GA4 and GA1. Has a small activity on GA29, producing GA8. Unable to convert GA20 to GA5, GA5 to GA3 or GA12 to GA14. Involved in the production of bioactive GA for vegetative growth and development, but not for the 3-beta-hydroxylation of GA in developing seeds.3 Publications

Catalytic activityi

Gibberellin 20 + 2-oxoglutarate + O2 = gibberellin 1 + succinate + CO2.3 Publications

Cofactori

Protein has several cofactor binding sites:
  • L-ascorbateBy similarity
  • Fe2+PROSITE-ProRule annotationNote: Binds 1 Fe2+ ion per subunit.PROSITE-ProRule annotation
