Snapshots of protein folding. A study on the multiple transition state pathway of cytochrome c(551) from Pseudomonas aeruginosa.

Abstract excerpt

Cytochrome c(551) (cyt c(551)) from Pseudomonas aeruginosa is a small protein (82 residues) that folds via a three-state pathway with the accumulation in the microsecond time-range of a compact collapsed intermediate. The presence of a single His residue, at position 16, permits the study of the refolding at pH 7.0 in the absence of miscoordination events. Here, we report on folding kinetics in the millisecond...
