    Tryptophan fluorescence measurements were used to characterize the local dynamics of the highly conserved glycine-rich loop (GRL) of the mitochondrial processing peptidase (MPP) subunit in the presence of the substrate precursor. Reporter tryptophan residue was introduced into the GRL of the yeast MPP (Y299W) or at a proximal site (Y303W). Timeresolved and steady-state fluorescence spectroscopy demonstrated that for Trp299, the primary contact with the yeast malate dehydrogenase precursor evokes a change of the local GRL mobility. Moreover, time-resolved measurements showed that a functionless MPP with a single-residue deletion in the loop (Y303W/G292) is defective particularly in the primary contact with substrate
