Identification and Characterization of a <i>Streptococcus pyogenes</i> Operon Involved in Binding of Hemoproteins and Acquisition of Iron

20 Feb 2003

Abstract excerpt

The hemolytic Streptococcus pyogenes can use a variety of heme compounds as an iron source. In this study, we investigate hemoprotein utilization by S. pyogenes. We demonstrate that surface proteins contribute to the binding of hemoproteins to S. pyogenes. We identify an ABC transporter from the iron complex family named sia for streptococcal iron acquisition, which consists of a lipoprotein (siaA), membrane...
