Ultrafast folding of α(3)D: A de novo designed three-helix bundle protein

Here, we describe the folding/unfolding kinetics of α(3)D, a small designed three-helix bundle. Both IR temperature jump and ultrafast fluorescence mixing methods reveal a single-exponential process consistent with a minimal folding time of 3.2 ± 1.2 μs (at ≈50°C), indicating that a protein can fold...
