EC	2.5.1.27
Accepted name:	adenylate dimethylallyltransferase (AMP-dependent)
Reaction:	prenyl diphosphate + AMP = diphosphate + N6-prenyladenosine 5′-phosphate
Glossary:	prenyl = 3-methylbut-2-en-1-yl = dimethylallyl (ambiguous)
Other name(s):	cytokinin synthase (ambiguous); isopentenyltransferase (ambiguous); 2-isopentenyl-diphosphate:AMP Δ2-isopentenyltransferase; adenylate isopentenyltransferase (ambiguous); IPT; adenylate dimethylallyltransferase; dimethylallyl-diphosphate:AMP dimethylallyltransferase
Systematic name:	prenyl-diphosphate:AMP prenyltransferase
Comments:	Involved in the biosynthesis of cytokinins in plants. Some isoforms from the plant Arabidopsis thaliana are specific for AMP while others also have the activity of EC 2.5.1.112, adenylate dimethylallyltransferase (ADP/ATP-dependent).
