CC -!- FUNCTION: Key oxidase enzyme in the biosynthesis of gibberellin that
CC catalyzes the conversion of GA12 and GA53 to GA9 and GA20 respectively,
CC via a three-step oxidation at C-20 of the GA skeleton.
CC {ECO:0000269|PubMed:16160850}.

CC -!- COFACTOR:
CC Name=L-ascorbate; Xref=ChEBI:CHEBI:38290; Evidence={ECO:0000250};
CC -!- TISSUE SPECIFICITY: Expressed in nodes and the ear of the elongating
CC stem. {ECO:0000269|PubMed:16160850}.
