IntEnz Enzyme Nomenclature
EC 2.5.1.27

Names

Accepted name:
adenylate dimethylallyltransferase (AMP-dependent)
Other names:
2-isopentenyl-diphosphate:AMP Δ2-isopentenyltransferase
adenylate isopentenyltransferase [ambiguous]
cytokinin synthase [ambiguous]
isopentenyltransferase [ambiguous]
Systematic name:
dimethylallyl-diphosphate:AMP dimethylallyltransferase

Reaction

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).
