Conformational Cycle of a Single Working Enzyme
نویسنده
چکیده
By simultaneous analysis of the on-time distribution and autocorrelation function of a single working cholesterol oxidase enzyme, a diffusional model reveals the coupling of conformation change with enzyme action. Activesite oxidation induces a conformational change that opens the path for substrate entry. Its binding, in turn, induces the reverse protein relaxation process, which tightens the active site, thereby reducing the rate of product release.

Functional conformational motions in the turnover cycle of cholesterol oxidase.
Reexamining experimental data of single-molecule fluorescence correlation spectroscopy for cholesterol oxidase, we find that the existing Michaelis-Menten models with dynamical disorder cannot explain strong correlations between subsequent turnover cycles revealed in the diagonal feature in the joint statistical distribution of adjacent "on" times of this enzyme. We suggest that functional conf...
متن کاملConformational-relaxation models of single-enzyme kinetics.
Fluorescent spectroscopy experiments with single-enzyme molecules yield a large volume of statistical data that can be analyzed and interpreted using stochastic models of enzyme action. Here, we present two models, each based on the mechanism that an enzyme molecule must pass through a sequence of conformational transformations to complete its catalytic turnover cycle. In the simplest model, on...
متن کاملAmplification and detection of single-molecule conformational fluctuation through a protein interaction network with bimodal distributions.
A protein undergoes conformational dynamics with multiple time scales, which results in fluctuating enzyme activities. Recent studies in single-molecule enzymology have observe this "age-old" dynamic disorder phenomenon directly. However, the single-molecule technique has its limitation. To be able to observe this molecular effect with real biochemical functions in situ, we propose to couple th...
متن کاملTwo-dimensional reaction free energy surfaces of catalytic reaction: effects of protein conformational dynamics on enzyme catalysis.
We introduce a two-dimensional (2D) multisurface reaction free energy description of the catalytic cycle that explicitly connects the recently observed multi-time-scale conformational dynamics as well as dispersed enzymatic kinetics to the classical Michaelis-Menten equation. A slow conformational motion on a collective enzyme coordinate Q facilitates the catalytic reaction along the intrinsic ...
متن کاملSimulation of a New Hybrid Solar and Organic Cycle as a Combined Cooling, Heat and Power (CCHP) Unit in Off Design Condition
In this paper, using parabolic mirrors, a solar field was designed, which was related to a storage tank for a residential complex in the city of Tafresh located in the center of Iran. The design was performed for the existing oils: VP1, THERMINOL 66, THERMINOL 59. Finally, considering an organic cycle with R123 as working fluid and assuming a minimum length required for oil flow rate to reach a...
