Journal ArticleDOI
Dynamics of ligand binding to myoglobin
TL;DR: The nonexponential rebinding observed at low temperatures and in solid samples implies that the innermost barrier has a spectrum of activation energies, similar to how myoglobin achieves specificity and order.
Journal ArticleDOI
Activation Energy Spectrum of a Biomolecule: Photodissociation of Carbonmonoxy Myoglobin at Low Temperatures
TL;DR: Carbon monoxide bound to myoglobin can be photodissociated with high quantum yield and rebinding can be described by a function of the form ${t}_{0}$, where $n$ and $H(t)={(1+\frac{t}{{t}\ensuremath{-}n}$ are temperature-dependent parameters.
Journal ArticleDOI
Tunneling in ligand binding to heme proteins.

TL;DR: Rebinding of carbon monoxide to the beta chain of hemoglobin after photodissociation by a laser flash is intramolecular below about 200 K; above 25 K, rebinding occurs via classical over-the-barrier motion; below, quantum-mechanical tunneling dominates.
Journal ArticleDOI
Dynamics of carbon monoxide binding by heme proteins.
TL;DR: Rebinding of carbon monoxide to myoglobin and to cytochrome P-450 after removal by a light flash occurs down to 50�K for myoglobin in glycerol-water solution.
Journal ArticleDOI
Transient analyzer with logarithmic time base
Robert H. Austin,K. W. Beeson,Shirley S. Chan,P. G. Debrunner,R. Downing,L. Eisenstein,Hans Frauenfelder,Thomas M. Nordlund +7 more
TL;DR: In this article, a digital analyzer is described that records smoothly and in one sweep transient processes over more than eight orders of magnitude in time, a typical sweep covers the time range from 2 μsec to 5 min.
