Cooperative Allosteric Transitions01:58

Cooperative Allosteric Transitions

7.9K
Cooperative allosteric transitions can occur in multimeric proteins, where each subunit of the protein has its own ligand-binding site. When a ligand binds to any of these subunits, it triggers a conformational change that affects the binding sites in the other subunits; this can change the affinity of the other sites for their respective ligands. The ability of the protein to change the shape of its binding site is attributed to the presence of a mix of flexible and stable segments in the...

Area of Science:

  • Interdisciplinary research combining chemistry, physics, and biology.
  • Focus on systems chemistry and bio/chemical information and communication technology (bio/chemical ICT).

Background:

  • Biological systems utilize chemical signals for communication.
  • Microfluidics and emulsions offer controlled environments for studying chemical dynamics.
  • The Belousov-Zhabotinsky reaction serves as a model for oscillatory chemical systems.

Purpose of the Study:

  • To investigate chemical signal propagation and synchronization in confined microenvironments.

  • To model biological communication strategies using engineered chemical oscillators.

Main Methods:

  • Utilized droplet-based microfluidics for creating water-in-oil microdroplets.
  • Employed emulsions with engineered interfacial properties (charge, stacking, defects).
  • Used the Belousov-Zhabotinsky reaction as a model chemical oscillator within microreactors.

Main Results:

  • Demonstrated emergent dynamical behaviors in arrays of micro-oscillators.
