Synthetic Biology

5.5K
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.

Background:

  • The Protein Data Bank (PDB) is a public repository for experimental protein structure models.
  • Accurate protein models are crucial for understanding biological functions and developing therapeutics.
  • Citizen science initiatives can crowdsource solutions to complex scientific problems.

Purpose of the Study:

  • To introduce and evaluate a new series of Foldit puzzles designed to improve the accuracy of protein models in the PDB.
  • To establish a mechanism for integrating Foldit player contributions into the official structural biology record.
  • To assess the impact of citizen science on the quality of protein structure data.

Main Methods:

  • Development of specialized Foldit puzzles focused on refining protein models.
  • Analysis of player performance and the extent of structural improvements achieved.
  • Integration of Foldit-derived refined models into the PDB-REDO databank for validation and dissemination.

Main Results:

  • Foldit players successfully improved the accuracy of deposited protein structures in the PDB.
  • The proposed mechanism effectively fed player contributions back into the scientific record.
  • Significant enhancements were observed in the quality of protein models refined by citizen scientists.

Conclusions:

  • Citizen science, exemplified by Foldit, offers a powerful approach to enhance the quality of structural biology data.
  • The integration of citizen science efforts into databases like PDB-REDO advances scientific reproducibility and data integrity.
  • Engaging the public in scientific endeavors like protein modeling is vital for scientific progress.
