Induced fit, conformational selection and independent dynamic segments: an extended view of binding events

Abstract

Single molecule and NMR measurements of protein dynamics increasingly uncover the complexity of binding scenarios. Here, we describe an extended conformational selection model that embraces a repertoire of selection and adjustment processes. Induced fit can be viewed as a subset of this repertoire, whose contribution is affected by the bond types stabilizing the interaction and the differences between the interacting partners. We argue that protein segments whose dynamics are distinct from the rest of the protein ('discrete breathers') can govern conformational transitions and allosteric propagation that accompany binding processes and, as such, might be more sensitive to mutational events. Additionally, we highlight the dynamic complexity of binding scenarios as they relate to events such as aggregation and signalling, and the crowded cellular environment.

  • Even if P(Ap) is taken equal to 1 and localization probability is eliminated by collapsing chance to necessity, P(Ac) can still pose huge obstacles to the chance configuration of the quaternary structure of operative biological systems.

    “Even if we take P (A p ) equal to 1, and thus assume there are no problematic obstacles involved in generating the building blocks; and also eliminate the localization probability by collapsing chance to necessity (selforganization), P(A c ) can still pose huge obstacles to the chance configuration of the quaternary structure of operative biological systems (Csermely et al., 2010).”

    The section on binding in the crowded cellular environment discusses factors that increase and decrease protein encounters, while the section on chaperones describes how they facilitate protein-complex assembly. Neither addresses P(Ac), the assumption that P(Ap) equals 1, or a claimed probability obstacle to forming functional quaternary structures by chance (searched those terms and paraphrases).

  • Propagation of conformational change at certain locations can cause large-amplitude fluctuations of linked domains.

    “The propagation of conformational change at certain locations228–230 can lead to large amplitude fluctuations of the linked domains.231”
  • In the induced fit mechanism, ligands bind to the single open protein structure and interaction with a rigid binding partner induces a conformational change.

    “In an induced fit scenario, the ligands bind to the single “open” protein structure and the interaction between a protein and a rigid binding partner induces a conformational change in the protein.”

  • Evidence points to the conformational selection binding mechanism, which allows one to precompute the conformational ensemble of the interacting molecule(s) and dock the separate conformers with limited conformational search.

    “In a long-standing debate between the proponents of the “induced-fit” and the “conformational selection” binding mechanisms [21–23], the evidence pointing to the latter allows one to precompute the conformational ensemble of the interacting molecule(s) and dock the separate conformers with limited conformational search [24,25].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
