β subunit domain essential for F1 rotation. (a) β Subunit domain between β-sheet4 and P-loop. A β subunit domain is shown for an (i) empty (βE) β subunit or (ii) ATP bound (βTP). The positions of Ser174, Gly149 and ATP are shown according to the bovine F1 (Abrahams et al. 1994). (b) Effects of the βPhe174 mutation and a second mutation (βGly149Ala) on rotation. Fitted curves were obtained from the histogram of the single revolution time of the wild-type and mutant F1 (wild-type, black solid curve; Phe174, grey solid curve; Phe174/Ala149, grey dashed curve; and Ala149, black dashed curve).
