Q9C7Z1 · G2OX4_ARATH

Function

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

Cofactor

Fe2+ (UniProtKB | Rhea| CHEBI:29033 )

Note: Binds 1 Fe2+ ion per subunit.

Pathway

Plant hormone biosynthesis; gibberellin biosynthesis.
