CC -!- FUNCTION: Involved in gibberellin (GA) biosynthesis. Catalyzes three
CC successive oxidations of ent-kaurenoic acid giving gibberellin 12
CC (GA12), a key step in GAs biosynthesis. GAs, which are involved many
CC processes, including stem elongation, play a central role in plant
CC development (Probable). Required for pollen germination and elongation
CC (PubMed:18083909). {ECO:0000269|PubMed:18083909,
CC ECO:0000305|PubMed:15075394}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ent-kaur-16-en-19-oate + 3 O2 + 3 reduced [NADPH--hemoprotein
CC reductase] = gibberellin A12 + 4 H(+) + 4 H2O + 3 oxidized [NADPH--
CC hemoprotein reductase]; Xref=Rhea:RHEA:33219, Rhea:RHEA-COMP:11964,

CC Evidence={ECO:0000250|UniProtKB:O23051};
CC -!- COFACTOR:
CC Name=heme; Xref=ChEBI:CHEBI:30413;
CC Evidence={ECO:0000250|UniProtKB:P04798};
CC -!- PATHWAY: Plant hormone biosynthesis; gibberellin biosynthesis.
CC {ECO:0000305}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000250|UniProtKB:O23051}; Single-pass membrane protein
CC {ECO:0000255}.
CC -!- TISSUE SPECIFICITY: Expressed in roots and panicles. Expressed at low
CC levels in vegetative shoot apices, leaf sheaths, leaf blades and stems.
CC {ECO:0000269|PubMed:15075394}.
CC -!- DISRUPTION PHENOTYPE: Severe dwarf phenotype without flower or seed
CC development. {ECO:0000269|PubMed:15075394}.
CC -!- SIMILARITY: Belongs to the cytochrome P450 family. {ECO:0000305}.
