Abstract

Tryptophan-induced quenching of fluorophores (TrIQ) uses intramolecular fluorescence quenching to assess distances in proteins too small (a) to this movement is relatively low (∼1.5-2.5 kcal/mol). Together, these results demonstrate that TyrIQ, used together with TrIQ, significantly expands the power of quenching-based distance mapping SDFL studies.
