Crystal structures of the catalytic subunit α of cAMP-dependent protein kinase (PKAc) with three adenosine analogue-oligoarginine conjugates (ARCs) are presented. The rationally designed ARCs include moieties that, in combination, target both the ATP- and the peptide-substrate-binding sites of PKAc, thereby taking advantage of high-affinity binding interactions offered by the ATP site while utilizing an additional mechanism for target specificity via binding to the peptide substrate site ...
