complex with the inhibitor protein (IF1). The F1–IF1 complex was solubilized and purified.
The question addressed was if this naturally occurring complex existed as monomers or
dimers. Size exclusion chromatography and electron microscopy showed that most of the
purified F1–IF1 complex was a dimer of two F1–IF1. As determined by the former method,
the relative concentrations of dimeric and monomeric F1–IF1 depended on the …
