| Addtional Information | FUNCTION:Catalyzes the oxidation of cytokinins, a family of N(6)- substituted adenine derivatives that are plant hormones, where the substituent is an isopentenyl group.CATALYTIC ACTIVITY:N(6)-dimethylallyladenine acceptor H(2)O = adenine 3-methylbut-2-enal reduced acceptor.COFACTOR:FAD (By similarity).BIOPHYSICOCHEMICAL PROPERTIES:Kinetic parameters: KM=1.3 uM for isopentenyladenine; Vmax=6.1 nmol/h/mg enzyme;ALTERNATIVE PRODUCTS:Event=Alternative splicing; Named isoforms=1; Comment=A number of isoforms are produced. According to EST sequences; Name=1; IsoId=Q9FUJ2-1; Sequence=Displayed;TISSUE SPECIFICITY:Expressed in trichomes and in developing stomata of young growing leaves. Strong expression in stipules and in the root cap, but not detected in the root meristem.DEVELOPMENTAL STAGE:High expression in stomatal meristemoids, but ceased during the differentiation of guard cells.SIMILARITY:Belongs to the oxygen-dependent FAD-linked oxidoreductase family. |
