In Escherichia coli F1F0-ATP synthase, the two b subunits form the second stalk spanning the distance between the membrane F0 sector and the bulk of F1. Current models predict that the stator should be relatively rigid and engaged in contact with F1 at fixed points. To test this hypothesis, we constructed a series of deletion mutations in the uncF(b) gene to remove segments from the middle of the second stalk of the subunit. Mutants with deletions of 7 amino acids were essentially normal, and… CONTINUE READING
