The periplasmic proteome of Yersinia pestis strain KIM6+ was characterized using differential 2-DE display of proteins isolated from several subcellular fractions. Circa 160 proteins were designated as periplasmic, including 62 (putative) solute-binding proteins of ATP-binding cassette (ABC) transporters (SBPs) and 46 (putative) metabolic enzymes.

Yersinia pestis proteins were sequentially extracted from crude membranes with a high salt buffer (2.5 M NaBr), an alkaline solution (180 mM Na2CO3, pH 11.3) and membrane denaturants (8 M urea, 2 M thiourea and 1% amidosulfobetaine-14). Separation of proteins by 2D gel electrophoresis was followed by identification of more than 600 gene products by MS. Data(More)
A computational technique is presented for the automated assignment of the multiple charge and multimer states (ionization states) in the time-of-flight (TOF) domain for matrix-assisted laser desorption/ionization (MALDI) spectra. Examples of the application of this technique include an improved, automatic calibration over the 2 to 70 kDa mass range and a(More)
