Towards the high-throughput expression of metallo­proteins from the Mycobacterium tuberculosis genome

JOURNAL OF SYNCHROTRON RADIATION, Issue 1 2005
John F. Hall
The provision of high-quality protein in adequate quantities is a prerequisite for any structural genomics programme. A number of proteins from the Mycobacterium tuberculosis genome have been expressed and the success at each stage of the process assessed. Major difficulties have been encountered in the purification and solubilization of many of these proteins, most likely as a result of mis-folding. Some improvements have been made to the protocol but the overall success rate is still limited; however, the use of a cell-free protein expression system will circumvent some of the difficulties encountered. Alternative purification systems are also required and the properties of a mutant blue copper protein are described, that may offer a combined purification and tagging system. [source]


A structural genomics initiative on yeast proteins

JOURNAL OF SYNCHROTRON RADIATION, Issue 1 2003
Sophie Quevillon-Cheruel
A canonical structural genomics programme is being conducted at the Paris-Sud campus area on baker's yeast proteins. Experimental strategies, first results and identified bottlenecks are presented. The actual or potential contributions to the structural genomics of several experimental structure-determination methods are discussed. [source]


Structure of a putative ,-phosphoglucomutase (TM1254) from Thermotoga maritima

ACTA CRYSTALLOGRAPHICA SECTION F (ELECTRONIC), Issue 12 2009
Richard W. Strange
The structure of TM1254, a putative ,-phosphoglucomutase from T. maritima, was determined to 1.74,Å resolution in a high-throughput structural genomics programme. Diffraction data were obtained from crystals belonging to space group P22121, with unit-cell parameters a = 48.16, b = 66.70, c = 83.80,Å, and were refined to an R factor of 19.2%. The asymmetric unit contained one protein molecule which is comprised of two domains. Structural homologues were found from protein databases that confirmed a strong resemblance between TM1254 and members of the haloacid dehalogenase (HAD) hydrolase family. [source]


Structure of purine nucleoside phosphorylase (DeoD) from Bacillus anthracis

ACTA CRYSTALLOGRAPHICA SECTION F (ELECTRONIC), Issue 5 2005
Rosa Grenha
Protein structures from the causative agent of anthrax (Bacillus anthracis) are being determined as part of a structural genomics programme. Amongst initial candidates for crystallographic analysis are enzymes involved in nucleotide biosynthesis, since these are recognized as potential targets in antibacterial therapy. Purine nucleoside phosphorylase is a key enzyme in the purine-salvage pathway. The crystal structure of purine nucleoside phosphorylase (DeoD) from B. anthracis has been solved by molecular replacement at 2.24,Å resolution and refined to an R factor of 18.4%. This is the first report of a DeoD structure from a Gram-positive bacterium. [source]


Metallogenomics and biological X-ray absorption spectroscopy

JOURNAL OF SYNCHROTRON RADIATION, Issue 1 2005
Isabella Ascone
An overview of the second special issue of the journal on biological applications of X-ray absorption spectroscopy (BioXAS) is presented. The emphasis is on the study of metalloproteins in the context of structural genomics programmes (metallo­genomics). [source]
