ENZYME entry: EC 2.5.1.112

Accepted Name
Adenylate dimethylallyltransferase (ADP/ATP-dependent).
Alternative Name(s)
Adenylate isopentenyltransferase.
Cytokinin synthase.
Isopentenyltransferase.
Reaction catalysed
  • Dimethylallyl diphosphate + ADP <=> diphosphate + N6-(dimethylallyl)adenosine diphosphate
  • Dimethylallyl diphosphate + ATP <=> diphosphate + N6-(dimethylallyl)adenosine triphosphate
Comment(s)
  • Involved in the biosynthesis of cytokinins in plants.
  • The IPT4 isoform from the plant Arabidopsis thaliana is specific for ADP and ATP.
  • Other isoforms, such as IPT1 from Arabidopsis thaliana and the enzyme from the common hop, Humulus lupulus, also have a lower activity with AMP (cf. EC 2.5.1.27).
  • Formerly EC 2.5.1.n4.
