In a recent work [1], we used extensive atomistic molecular dynamics simulations with explicit solvent to study the binding of an SH3 domain with its binding partner as a general example for protein binding mediated by modular protein domains.
For example, screening for binding elements in RNA sequences comparable to the approach implemented for the PTBs, Nova, and Pumilio in this study could be readily performed for any RBP of interest.
Site-directed mutagenesis on conserved amino-acid residues from the family sequence pattern or considered functionally relevant (for example, for substrate binding) was carried out.
Supplementary Video S4 provides an example for the binding model, describing how to set up equations for the second-order association reaction and first-order dissociation.
N-Cyclopentyl 68, N-cyclohexyl 69 and ester 70 were also selected as representative examples for CB2R/CB1R binding affinity studies.
Nevertheless, it is likely that the three conformers have slightly different properties, for example binding affinity for other proteins.
The presence of hydrophobic surface residues, for example, binding sites for other proteins, and the denaturation of otherwise folded proteins lead to the exposure of hydrophobic residues to water and reduce solubility, sometimes leading to aggregation and precipitation.
Oxidized derivatives of cholesterol with biological activity, for example, as binding partners for nuclear receptors.
For example, a binding site for an effector molecule (i.e., a nucleic acid that will affect the activity of a functional nucleic acid) may be required to be complementary to a sequence released in a preceding step.
Binding of phospholipids to the annular sites on KcsA shows limited selectivity with, for example, a binding constant for phosphatidic acid relative to DOPC of ∼2.0.
