Abstract
We present a complete theoretical and computational framework for protein folding mediated by the GroEL chaperonin, basedon phase-locking dynamics of hydrogen bond networks. We establish three fundamental results: (1)protein hydrogen bonds constitute coupled pro
ton oscillators operating at frequenciesω∼10^13−10^14Hz;(2)the GroEL cavity provides a time-varying resonanc eenvironment through ATP-driven cycles that scan frequency space
at harmonics of the cytoplasmic O2 masterclock (ωO2
=1013Hz);
(3)protein folding proceeds through the cycle-by-cycle establishment of phase-locked hydrogen bond clusters,
with earlier-cycle bonds acting as nucleation sites for later-cycle bonds through a causal dependency structure.
We derive the phase-locking equations from first principles using Kuramoto dynamics,
prove that the native protein structure corresponds to the global minimum of phase variance across the hydrogen bond network and present a reverse folding algorithm tht reveals complete folding pathway by tracking formation cycles. Computational validation model demonstrates successful folding in 4-11 ATP cycles within a final phase coherence ⟨r⟩>0.8, dependency graphs showing clear folding nuclei, and quantitative agreement between predicted and observed cycle-by-cycle bond formation. This work provides a rigorous mathematical foundation for chaperon-mediated folding as an active phase-locking process, explains the necessity of multiple ATP cycles and establishes a computational method for determining folding pathways from the native structure.
