N 6 -isopentenyladenosine (i 6 A, riboprin ) is a rare nucleoside and occurs in the tRNA . It consists of β- D- ribofuranose (sugar) and N 6 -isopentenyladenine . It differs from adenosine by adding an isopentenyl group on the amino group . The adenosine is converted with isopentenyl pyrophosphate by means of the tRNA isopentenyl transferase to form N 6 -isopentenyl adenosine. Like N 6 -threonylcarbamoyladenosine , it is found in addition to the anticodon at position 37 in tRNA in both bacteria and eukaryotes .

A tRNA Sec from Escherichia coli .
N 6 -isopentenyladenosine is marked with i 6 A here .
