Cloning, production, and purification of proteins for a medium-scale structural genomics project.

The South-Paris Yeast Structural Genomics Pilot Project (http://www.genomics.eu.

Refolding strategies from inclusion bodies in a structural genomics project.

The South-Paris Yeast Structural Genomics Project aims at systematically expressing, purifying and determining the structure of S. cerevisiae proteins with no detectable homology to proteins of known structure. We brought 250 yeast ORFs to expression in E.

Crystal structure of the YGR205w protein from Saccharomyces cerevisiae: close structural resemblance to E. coli pantothenate kinase.

The protein product of the YGR205w gene of Saccharomyces cerevisiae was targeted as part of our yeast structural genomics project. YGR205w codes for a small (290 amino acids) protein with unknown structure and function. The only recognizable sequence feature is the presence of a Walker A motif (P loop) indicating a possible nucleotide binding/converting function.

Crystal structure of the yeast Phox homology (PX) domain protein Grd19p complexed to phosphatidylinositol-3-phosphate.

Phox homology (PX) domains have been recently identified in a number of different proteins and are involved in various cellular functions such as vacuolar targeting and membrane protein trafficking. It was shown that these modules of about 130 amino acids specifically binding to phosphoinositides and that this interaction is crucial for their cellular function. The yeast genome contains 17 PX domain proteins.
