Using a zeatin affinity column a 40 kDa protein was isolated from tobacco Bright Yellow 2 (TBY-2) and identified by mass spectrometry as adenosine kinase.

Individual types of cytokinins in plants are interconverted to their respective forms by several enzymatic activities (5'-AMP-isopentenyltransferase, adenosine nucleosidase, 5'-nucleotidase, adenosine phosphorylase, adenosine kinase, trans-hydroxylase, zeatin reductase, beta-glucosidase, O-glucosyl transferase, N-glucosyl transferase, cytokinin oxidase).

The four TBY-2 ADK isoforms (designated 1S, 2S, 1T, and 2T) display a high affinity for both adenosine (Km 1.88-7.30 microm) and three distinct types of cytokinin ribosides: isopentenyladenosine; zeatin riboside; and dihydrozeatin riboside (Km 0.30-8.71 microm).
