Two sample preparation methods based on electrostatic binding were tested to simultaneously separate different viral particles from different food surfaces (lettuce, strawberry, raspberries and green onions).
It is likely that the interaction of these molecules with muscarinic receptors is based on electrostatic binding since two other molecules with similar interaction with muscarinic receptors, LCT and acetylcholine, share overall charge composition but not the atomic alignment [26], [27].
The FHA domain is linked to the kinase/phosphatase catalytic domain by a flexible tether, and it exhibits a mode of target selection based on electrostatic complementarity between the binding surface and the phosphothreonine peptide.
The binding of the tau-heparin complex is based on electrostatic interactions, but the exact binding mode of heparin to the tau protein has not been fully identified.
In related studies, Tsuchiya et al. [ 3] used a structure-based method to identify protein-DNA binding sites based on electrostatic potentials and surface shape.
The binding affinity of heparin-binding growth factors with heparin is mainly based on electrostatic interactions [ 21], which is critical for storage, release, and protection of the growth factor from degradation [ 22].
However, given that the first acidic region, STDE, of hTFIIEα has no effect on the binding, the interaction is not merely based on electrostatic interactions.
For example, many micro-nanomanipulators, like the microgripper, are designed based on electrostatic mechanism [82],[82].
This situation is explained based on electrostatic repulsion forces between surface positive charges and Pb species.
As none of these proteins contains any of the identifiable cell-binding peptide motifs, such as the arginine-glycine-aspartic acid (RGD) sequence, the process of cell attachment has been suggested to be non-specific, likely based on electrostatic interactions (Minoura et al. 1995b).
Among 1682 protein-metal ion complexes, 639 involve both coordination bonds and electrostatic force, 459 are based on electrostatic force but with no coordination bonds, and 499 incorporate coordination bonds with no electrostatic force.
