  • FUNCTION Cytokinin-activating enzyme working in the direct activation pathway. Controls the shoot meristem activity. Phosphoribohydrolase that converts inactive cytokinin nucleotides to the biologically active free-base forms. Reacts specifically with cytokinin nucleoside 5'-monophosphates, but not with di- or triphosphate.CATALYTIC ACTIVITY N(6)-(dimethylallyl)adenosine 5'-phosphate + H2O = N(6)-dimethylallyladenine + D-ribose 5-phosphateCATALYTIC ACTIVITY 9-ribosyl-trans-zeatin 5'-phosphate + H2O = trans-zeatin + D-ribose 5-phosphateBIOPHYSICOCHEMICAL PROPERTIES can also use benzyladenosine 5'-phosphate as substrate, but no activity with cytokinin ribosides.SUBCELLULAR LOCATION Expressed in roots, leaves, stems, tiller buds, immature inflorescences and flowers. Expressed in the upper part of shoot meristems, including axillary meristems, meristems of developing panicle and floral meristems.DISRUPTION PHENOTYPE Premature termination of the floral meristem.MISCELLANEOUS The name lonely guy came from the fact that flowers of the mutants often contained only one stamen but no pistil.SIMILARITY Belongs to the LOG family.
