CC -!- FUNCTION: Catalyzes the oxidation of cytokinins, a family of N(6)-
CC substituted adenine derivatives that are plant hormones, where the
CC substituent is an isopentenyl group. {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=A + H2O + N(6)-dimethylallyladenine = 3-methyl-2-butenal +
CC adenine + AH2; Xref=Rhea:RHEA:13625, ChEBI:CHEBI:13193,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15825, ChEBI:CHEBI:16708,
CC ChEBI:CHEBI:17499, ChEBI:CHEBI:17660; EC=1.5.99.12;
CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692; Evidence={ECO:0000250};
CC -!- SUBUNIT: Monomer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Secreted, extracellular space {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the oxygen-dependent FAD-linked oxidoreductase
CC family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=EAZ22265.1; Type=Frameshift; Evidence={ECO:0000305};
