Deoxycytidine Monophosphate 244-248 ribonuclease A family member 4 Homo sapiens 70-77 26748441-5 2016 These structures provide insight into the structural basis of the uridine versus cytosine substrate specificity in RNase 4: in the D80A mutant (D80A dCMP), the side chain of Arg101 is positioned further away from the substrate-binding pocket due to the loss of the Asp80 side chain, reducing the repulsion force on the less favoured dCMP from Arg101 and allowing the ligand to occupy the binding pocket.
