The self-association of puromycin has been studied using proton magnetic resonance spectroscopy. The concentration, temperature and pH dependence studies of the proton chemical shifts of the adenine protons indicate that puromycin in aqueous solution at pD 7.4 self associates predominantly through adenine-adenine interaction. At this pD, the amino group of the aminoacyl segment of puromycin has been demonstrated to exist in a equilibrium blend of protonated and non-protonated forms. At pD 2.6, PM is found to exist predominantly in the monomeric from in which the methyl groups of the 6N-dimethyladenine are found to be non-equivalent due to hindered rotation about the C6-N6 bond.
