Conversion of N⁶-(Δ²-Isopentenyl)adenosine to Adenosine by Enzyme Activity in Tobacco Tissue

Abstract

By using [8-(14)C]-N(6)-(Delta(2)-isopentenyl)adenosine as a substrate, we detected the presence of enzyme activity in a crude extract of tobacco tissue that converts this cytokinin into adenosine. The extract also contains strong hydrolase activity that converts adenosine to adenine.
