Dynamic mechanisms driving conformational conversions of the β and ε subunits involved in rotational catalysis of F^sub 1^-ATPase

F-type ATPase is a ubiquitous molecular motor. Investigations on thermophilic F1-ATPase and its subunits, β and ε, by NMR were reviewed. Using specific isotope labeling, pKa of the putative catalytic carboxylate in β was estimated. Segmental isotope-labeling enabled us to monitor most residues of β,...
