Electrostatic contributions to the kinetics and thermodynamics of protein assembly.
The role of electrostatic interactions in the assembly of a native protein structure was studied using fragment complementation. Contributions of salt, pH, or surface charges to the kinetics and equilibrium of calbindin D(9k) reconstitution was measured in the presence of Ca(2+) using surface plasmon resonance and isothermal titration calorimetry. Whereas surface charge substitutions primarily ...
متن کاملElectrostatic contributions to heat capacity changes of DNA-ligand binding.
Significant heat capacity changes (DeltaCp) often accompany protein unfolding, protein binding, and specific DNA-ligand binding reactions. Such changes are widely used to analyze contributions arising from hydrophobic and polar hydration. Current models relate the magnitude of DeltaCp to the solvent accessible surface area (ASA) of the molecule. However, for many binding systems-particularly th...
متن کاملLong-Range Electrostatic Contributions to Protein-Ligand Binding Estimated Using Protein Charge Ladders, Affinity Capillary Electrophoresis, and Continuum Electrostatic Theory
Affinity capillary electrophoresis and protein charge ladders are used together to measure the contributions of long-range electrostatic interactions to binding of substituted benzene sulfonamide inhibitors to derivatives of human carbonic anhydrase II. The results are analyzed by continuum electrostatic calculations, which afford a detailed analysis of interactions of individual members of a p...
متن کاملElectrostatic and Steric Contributions to Block of the Skeletal Muscle Sodium Channel by μ-Conotoxin
Pore-blocking toxins are valuable probes of ion channels that underlie electrical signaling. To be effective inhibitors, they must show high affinity and specificity and prevent ion conduction. The 22-residue sea snail peptide, mu-conotoxin GIIIA, blocks the skeletal muscle sodium channel completely. Partially blocking peptides, derived by making single or paired amino acid substitutions in mu-...
متن کاملElectrostatic contributions to the stability of a thermophilic cold shock protein.
The thermophilic Bacillus caldolyticus cold shock protein (Bc-Csp) differs from the mesophilic Bacillus subtilis cold shock protein B (Bs-CspB) in 11 of the 66 residues. Stability measurements of Schmid and co-workers have implicated contributions of electrostatic interactions to the thermostability. To further elucidate the physical basis of the difference in stability, previously developed th...
