"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," researchers in the United States report.
