Synthesis of isoprenoid diphosphate mimetics

Abstract:

Cytokinins, are central regulators of cell division and differentiation in plants. Most naturally occurring cytokinins are 3,3-dimethylallyl adenine derivatives. Isopentenyladenine carries an unmodiefied isopentenyl side chain, whereas trans-zeatin and cis-zeatin carry hydroxylated side chains. Isopentenyltransferases (IPTs) are known to be responsible for the biosynthesis of cytokinins. The model plant Arabidopsis thaliana contains nine isozymes (AtIPT1 to AtIPT9). One type of isopentenyl-transferases modifies tRNA and is called tRNA-isopentenyltransferases (AtIPT2 and AtIPT9). The other type (AtIPT1, AtIPT3-8) catalyzes the transfer of the isopentenyl moiety from dimethylallyl-diphosphate (DMAPP) to the N-amino group of an adenosine moiety (AMP, ADP or ATP) (Scheme 1).
