  • Annereau, J.P.; Ko, Y.H.; Pedersen, P.L.
    Cystic fibrosis transmembrane conductance regulator: the NBF1+R (nucleotide-binding fold 1 and regulatory domain) segment acting alone catalyses a Co2+/Mn2+/Mg2+-ATPase activity markedly inhibited by both Cd2+ and the transition-state analogue orthovanadate (2003), Biochem. J., 371, 451-462.
