R‑Domain Phosphorylation by Protein Kinase A Stimulates Dissociation of Unhydrolyzed ATP from the First Nucleotide-Binding Site of the Cystic Fibrosis Transmembrane Conductance Regulator

The cystic fibrosis transmembrane conductance regulator (CFTR) is an asymmetric ATP-binding cassette transporter in which ATP hydrolysis occurs only at the second of the two composite nucleotide-binding sites whereas there are noncanonical substitutions of key catalytic residues in the first site. T...
