Antibody Evolution Constrains Conformational Heterogeneity by Tailoring Protein Dynamics
flexibility nonlinear spectroscopy fluorscein molecular recognition
2016/5/24
The evolution of proteins with novel function is thought to start from precursor proteins that are conformationally heterogeneous. The corresponding genes may be duplicated and then mutated to select ...
Electrostatic and Conformational Effects on the Electronic Structures of Distortional Isomers of a Mixed-Valence Binuclear Cu Complex
Electrostatic Conformational Electronic Structures Distortional Isomers Mixed-Valence Binuclear Cu Complex
2016/5/23
The electronic structure of the binuclear copper complex [Cu(2)(L)](3+) [L = N(CH(2)CH(2)N(H)CH(2)CH(2)N(H)CH(2)CH(2))(3)N] has been investigated by resonance Raman and electroabsorption spectroscopy....
Conformational Dynamics and Thermal Cones of C-terminal Tubulin Tails in Neuronal Microtubules
microtubule C-terminal tubulin tail neuronal excitation
2015/7/29
In this paper we present a model for estimation of the C-terminal tubulin tail (CTT) dynamics in cytoskeletal microtubules of nerve cells. We show that the screened Coulomb interaction between a targe...
The Conformational Gymnastics of the Escherichia Coli SecA Molecular Machine and its Interactions with Signal Sequences
SecA Signal sequences Molecular machines
2014/12/10
Protein secretion is a selective and regulated process that is essential in all organisms. In bacteria the preprotein translocase SecA, either free in the cytosol or associated with the SecYEG translo...
Probing for Conformational Changes in the Repair Enzyme Mfd Using Mutant Protein Constructs
Conformational Changes Repair Enzyme Mfd Mutant Protein Constructs
2014/12/9
DNA repair is essential for survival, as damage to the genome can interrupt the precarious balance of cell functions, causing further mutations and possibly leading to cancer. The bacterial transcript...
Mod-CSA: Modularity optimization by conformational space annealing
Mod-CSA Modularity optimization conformational space annealing
2012/2/24
We propose a new modularity optimization method, Mod-CSA, based on stochastic global optimization algorithm, conformational space annealing (CSA). Our method outperforms simulated annealing in terms o...
Protein Conformational Change Based on a Two-dimensional Generalized Langevin Equation
Protein conformational fluctuation Two-dimensional generalized Langevin equation Atomic packing density model Fractional Gaussian noise
2011/9/23
A two-dimensional generalized Langevin equation is proposed to describe the protein con-formational change, compatible to the electron transfer process governed by atomic packing density model. We ass...
Folding and unfolding of a triple-branch DNA molecule with four conformational states
Nonequilibrium systems, single-molecule experiments,optical tweezers, DNA
2011/6/10
Single-molecule experiments provide new insights into biological processes hitherto not accessible by measurements performed on bulk systems. We report on a study of the kinetics of a triple-branch DN...
Side-chain conformational changes upon protein-protein association
Side-chain conformational changes protein-protein association
2010/10/14
Conformational changes upon protein-protein association are the key element of the binding mechanism. The study presents a systematic large-scale analysis of such conformational changes in the side c...
SERS Measurements of Magnetic Stretching Force-Induced Trans-Gauche Conformational Change
SERS Measurements Force-Induced Trans-Gauche Conformational Change
2010/1/1
The effects of stretching forces on covalently bridged 3-mercaptopropanoic acid molecules between magnetic particles (MPs) and Ag nano-particles (NPs) were studied by surface-enhanced Raman scatterin...
