The unique conformation and orientational change of 5'-amino-5'-deoxyuridine in Kolthoff's buffer is discussed. From CD and NOE spectra, anomalous syn orientation of Urd-5'-NH2 might be caused by specific interaction between borates and Urd-5'-NH2, which promote the formation of hydrogen bonding between 2-carbonyl oxygen and hydrogen of 5'-amino group. This borates induced syn orientation of Urd-5'-NH2 could be applied to external stimulation control of target RNA/DNA hybridization.
