The Evidence for Evolution02:55

The Evidence for Evolution

48.3K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

Protein and Protein Structure02:15

Protein and Protein Structure

88.2K
Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules. Proteins may be structural, regulatory, contractile, or protective. They may serve in transport, storage, or membranes; or they may be toxins or enzymes. Their structures, like their functions, vary greatly. They are all, however, amino acid polymers arranged in a linear sequence.
A protein's shape is critical to its function. For example, an enzyme...

Structural Protein Function

30.0K
Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity.  In bones and teeth, it mineralizes to...

Convergent Evolution

33.0K
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

Area of Science:

  • Molecular Biology
  • Evolutionary Biology
  • Biochemistry

Background:

  • Canonical protein evolution relies on gene duplication and mutations.
  • Post-translational modifications also influence protein structure and function.

Purpose of the Study:

  • To identify novel mechanisms of protein evolution.
  • To investigate the role of structural capacitance in rapid evolution and disease.

Main Methods:

  • Survey of the human mutation database.
  • Analysis of protein microstructure generation in disordered regions.

Main Results:

  • Identified "structural capacitance" as a de novo microstructure generation mechanism.
  • Structural capacitance facilitates rapid, saltatory evolution.
  • Linked protein microstructure generated by this mechanism to human disease pathogenesis.

Conclusions:

  • Structural capacitance offers a distinct pathway for rapid protein evolution.
  • This mechanism presents a trade-off between evolutionary potential and disease risk.
  • Structural capacitance has implications for understanding protein fold diversification and synthetic protein design.
