Academic labs can adapt high-throughput protein production and crystallization methods for medium-throughput structural genomics. This approach successfully yielded multiple protein structures from Escherichia coli and Mycobacterium tuberculosis targets.

Area of Science:

  • Structural biology
  • Protein crystallography
  • Genomics

Background:

  • High-throughput protein studies are common in large structural genomics programs.
  • Medium-throughput methods for academic labs are less developed.
  • There's a need to adapt existing high-throughput techniques for smaller-scale research.

Purpose of the Study:

  • To adapt high-throughput methods for medium-throughput protein production and crystallization in an academic setting.
  • To report initial results from projects targeting Escherichia coli and Mycobacterium tuberculosis proteins.
  • To demonstrate the value of a medium-throughput approach for structural genomics.

Main Methods:

  • Developed sequential and iterative procedures for protein expression and crystallization.

  • Implemented new technical processes tailored for medium-throughput scale.
  • Applied these methods to target genes from Escherichia coli and Mycobacterium tuberculosis.

    • Main Results:

    • In 14 months, 108 target genes were pursued, yielding 69 soluble proteins.
    • 36 proteins were successfully crystallized, with 13 providing usable data sets.
    • 9 protein structures were determined, showcasing the approach's efficacy.

    Conclusions:

    • The developed medium-throughput approach is effective for academic structural genomics.
    • This strategy facilitates the determination of protein 3D structures for organisms like E. coli and M. tuberculosis.
    • Findings can inform future planning for protein expression and crystallization efforts in medium-throughput programs.
