CC -!- FUNCTION: Cytokinin-activating enzyme working in the direct activation
CC pathway. Phosphoribohydrolase that converts inactive cytokinin
CC nucleotides to the biologically active free-base forms (By similarity).
CC {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + N(6)-(dimethylallyl)adenosine 5'-phosphate = D-ribose 5-
CC phosphate + N(6)-dimethylallyladenine; Xref=Rhea:RHEA:48560,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:17660, ChEBI:CHEBI:57526,
CC ChEBI:CHEBI:78346; EC=3.2.2.n1;
CC -!- CATALYTIC ACTIVITY:
CC Reaction=9-ribosyl-trans-zeatin 5'-phosphate + H2O = D-ribose 5-
CC phosphate + trans-zeatin; Xref=Rhea:RHEA:48564, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:16522, ChEBI:CHEBI:78346, ChEBI:CHEBI:87947; EC=3.2.2.n1;
CC -!- SIMILARITY: Belongs to the LOG family. {ECO:0000305}.
