CC -!- FUNCTION: 2-oxoglutarate (OG)- and Fe(II)-dependent dioxygenase (2OGD)
CC involved in scopoletin biosynthesis (PubMed:22169019). Converts
CC feruloyl CoA into 6'-hydroxyferuloyl CoA, and, at low efficiency,
CC caffeoyl-CoA into 6'-hydroxycaffeate, but has no activity with p-
CC coumaroyl-CoA (PubMed:22169019). {ECO:0000269|PubMed:22169019}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(E)-feruloyl-CoA + 2-oxoglutarate + O2 = (E)-6-
CC hydroxyferuloyl-CoA + CO2 + succinate; Xref=Rhea:RHEA:57856,
CC ChEBI:CHEBI:15379, ChEBI:CHEBI:16526, ChEBI:CHEBI:16810,
CC ChEBI:CHEBI:30031, ChEBI:CHEBI:87305, ChEBI:CHEBI:142390;
CC EC=1.14.11.61; Evidence={ECO:0000269|PubMed:22169019};
CC -!- COFACTOR:
CC Name=L-ascorbate; Xref=ChEBI:CHEBI:38290;
CC Evidence={ECO:0000250|UniProtKB:Q9C899};
CC -!- COFACTOR:
CC Name=Fe(2+); Xref=ChEBI:CHEBI:29033;
CC Evidence={ECO:0000255|PROSITE-ProRule:PRU00805};
CC Note=Binds 1 Fe(2+) ion per subunit. {ECO:0000255|PROSITE-
CC ProRule:PRU00805};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=9.15 uM for feruloyl-CoA {ECO:0000269|PubMed:22169019};
CC Note=kcat is 2.68 sec(-1) with feruloyl-CoA as substrate.
CC {ECO:0000269|PubMed:22169019};
CC pH dependence:
CC Optimum pH is 6.5. {ECO:0000269|PubMed:22169019};
CC -!- PATHWAY: Phenylpropanoid metabolism. {ECO:0000269|PubMed:22169019}.
CC -!- TISSUE SPECIFICITY: Expressed at low levels in tubers, underground
CC stems, leaves and petioles. {ECO:0000269|PubMed:22169019}.
CC -!- INDUCTION: Transiently induced by fungal (F.oxysporum f.sp. batatas O-
CC 17) and chitosan treatments, in association with the accumulation of
CC umbelliferone and its glucoside (skimmin) in the tubers.
CC {ECO:0000269|PubMed:22169019}.
CC -!- SIMILARITY: Belongs to the iron/ascorbate-dependent oxidoreductase
CC family. {ECO:0000305}.
