Molecular Models

42.2K
Physical models representing molecular architectures of chemical compounds play essential roles in understanding chemistry. The use of molecular models makes it easier to visualize the structures and shapes of atoms and molecules.

Assembly of Signaling Complexes

6.1K
Multiprotein signaling complexes are formed in a dynamic process involving protein-protein interactions at the cytoplasmic domain of transmembrane receptors or enzymatic and non-enzymatic proteins associated with the receptor. These complexes ensure the activation and propagation of intracellular signals that regulate cell functions.

Intrinsically Disordered Proteins

18.7K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

Protein Networks

4.2K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Protein Complex Assembly

14.5K
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types.  Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.
Many viruses self-assemble into a fully functional unit using the infected host cell to...

Area of Science:

  • Supramolecular Chemistry
  • Molecular Computing
  • Constitutional Dynamic Chemistry

Background:

  • Constitutional dynamic chemistry (CDC) offers adaptive molecular computing but struggles with complex digital information processing.
  • Existing constitutional dynamic networks (CDNs) have limitations in handling intricate data.

Purpose of the Study:

  • To introduce a supramolecular CDN based on cyanine dye MTC aggregation (Agg-CDN) for advanced molecular computing.
  • To demonstrate the reconfigurability and spectroscopic distinguishability of the Agg-CDN for digital information processing.

Main Methods:

  • Formation of a supramolecular CDN (Agg-CDN) from four interconvertible MTC constituents: monomers, dimers, J-aggregates, and H-aggregates.
  • Reconfiguration of the Agg-CDN through constituent exchange triggered by chemical inputs.
  • Spectroscopic analysis to distinguish different Agg-CDN states based on MTC optical properties.

Main Results:

  • The Agg-CDN demonstrated reconfigurability in response to chemical stimuli.
  • At least nine unique, spectroscopically distinguishable states of the Agg-CDN were achieved.
  • The system successfully encoded and encrypted complex digital information, including multi-pixel images.

Conclusions:

  • The developed MTC-based Agg-CDN advances CDC for complex digital information processing.
  • This work establishes a new paradigm for adaptive molecular computing systems capable of handling intricate data.
  • The Agg-CDN shows potential for applications in chemical information storage, encryption, and image processing.
