This study details a structural genomics program on baker's yeast proteins, presenting experimental strategies and initial findings. It discusses the contributions of various structure-determination methods to advancing structural genomics.

Area of Science:

  • Structural biology
  • Proteomics
  • Yeast genetics

Background:

  • Structural genomics aims to determine the 3D structures of all proteins.
  • Baker's yeast (Saccharomyces cerevisiae) is a model organism for studying eukaryotic cell biology.
  • Understanding protein structures is crucial for deciphering biological functions.

Purpose of the Study:

  • To present the strategies and initial results of a structural genomics program focused on baker's yeast proteins.
  • To identify challenges and bottlenecks in the experimental workflow.
  • To evaluate the utility of different structure-determination methods in structural genomics.

Main Methods:

  • High-throughput protein expression and purification.
  • X-ray crystallography and Nuclear Magnetic Resonance (NMR) spectroscopy for structure determination.
