Research Abstract

In previous study, we proposed that a dynamic equilibrium betweenthe multiple bound states is the molecular mechanism of the broadly selective specificity ofthe Tom20 receptor towards the divergent mitochondrial presequences. In this study, wecarried out X-ray crystal structure analysis and NMR spectroscopy experiments using newcomplexes between Tom20 and presequenses. We attempted to express of full lengthTom20 protein.
