Delayed addition of GroEL WT and G192X mutants to fibrillation reactions of αSyn.
A–D, after initiating the fibril-forming reaction in the absence of chaperonin, either GroEL WT (A) or GroEL G192N (B), G192I (C), or G192W (D) mutant was added after a fixed delay time. The ratio of GroEL14 to αSyn added was fixed at 0.2:1. The specific time of delay before the addition of chaperonin to the experiment follows the following convention: red, chaperonin added at zero time (no delay); orange, chaperonin added after a 3-h (180-min) delay; green, chaperonin added after an 8-h (480-min) delay; blue, chaperonin added after a 24-h (1440-min) delay. Black traces indicate reactions in the absence of chaperonin. Error bars represent the S.E. of each data point.
