Protein Complexes with Interchangeable Parts

2.1K
Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.
The SCF ubiquitin ligase is a protein complex of five individual proteins. This complex attaches ubiquitin to other target proteins to mark them for degradation. In order...

DNA as a Genetic Template

22.1K
Two structural features of the DNA molecule provide a basis for the mechanisms of heredity: the four nucleotide bases and its double-stranded nature. The Watson-Crick model of double-helical DNA structure, proposed in 1952, drew heavily upon the X-ray crystallography work of researchers Rosalind Franklin and Maurice Wilkins. Watson, Crick, and Wilkins jointly received the Nobel Prize in Physiology or Medicine for their work in 1962. Franklin was, controversially, excluded from the prize for...

Synthetic Biology

4.4K
Synthetic biology is an interdisciplinary science that involves using principles from disciplines such as engineering, molecular biology, cell biology, and systems biology. It involves remodeling existing organisms from nature or constructing completely new synthetic organisms for applications such as protein or enzyme production, bioremediation, value-added macromolecule production, and the addition of desirable traits to crops, to name a few.

Single-Strand DNA Binding Proteins

12.8K
For successful DNA replication, the unwinding of double-stranded DNA must be accompanied by stabilization and protection of the separated single strands of the DNA. This crucial task is performed by single-strand DNA-binding (SSB) proteins. They bind to the DNA in a sequence-independent manner, which means that the nitrogenous bases of the DNA need not be present in a specific order for binding of SSB proteins to it. The binding of SSB proteins straightens single-stranded DNA (ssDNA) and makes...

Area of Science:

  • Bionanotechnology
  • Regenerative Medicine
  • Biomaterials Engineering

Background:

  • Developing defined protein-based materials is crucial for bionanotechnology and regenerative medicine.
  • Large repetitive sequences in structural and matrix proteins hinder their assembly and precise control.
  • Existing methods lack efficiency and reliability in creating tailored protein-based systems.

Purpose of the Study:

  • To introduce an efficient and reliable platform for the assembly and functionalization of protein-based materials.
  • To overcome challenges associated with the large repetitive sequences of structural and matrix proteins.
  • To enable the creation of diverse, modular biohybrid materials with tailored functions.

Main Methods:

  • Development of an integrative "one-vector-toolbox-platform" (OVTP).
  • Assembly, multimerization, and arrangement of defined molecular DNA-tecton libraries.
  • Direct translation and selective functionalization of protein-tecton libraries using genetically encoded unnatural amino acids (UAA).

Main Results:

  • The OVTP provides a fast, efficient, and reliable method for creating diverse protein-tectons (elastin, resilin, silk, epitope elements).
  • The platform allows for the assembly of modular biohybrid materials using multi-block domain genes and UAAs.
  • Functional expansion of protein-tecton libraries with chemical functionalities via UAA bioorthogonal reactivity was achieved.

Conclusions:

  • The OVTP facilitates access to a wide array of defined protein-based biohybrid materials.
  • This platform enables the creation of self-assembled superstructures like nanoreactors and nanobiomaterials.
  • The OVTP supports advancements in biotechnology and personalized regenerative medicine through modular material design.
