    ..A model is proposed that suggests that IF1 binds rapidly, but loosely to F(1) with two or three catalytic sites filled, and is then locked in the enzyme during catalytic hydrolysis of ATP. ..

    ..Moreover, the data obtained using chimeric PsaE-IF1 suggest that before binding IF1 presents to the enzyme with its middle part facing a catalytic interface and its Nter extremity folded in the opposite direction. ..
