C-20 gibberellin 2-beta-dioxygenase activity

Known as: C-20 GA 2-oxidase activity, C(20) gibberellin 2-oxidase activity, C-20 gibberellin 2-beta-hydroxylase activity 
Catalysis of the reaction: a C-20 gibberellin + 2-oxoglutarate + O2 = a C-20 2-beta-hydroxygibberellin + succinate + CO2. C-20 gibberellin refers to…
