Patent number: 7588762Abstract: A protein from Streptococcus pyogenes, serotype Ml has been characterized. This protein, called protein SIC, plays a role in S. pyogenes pathogenicity and virulence. It inhibits hemolysis by interacting with the plasma proteins clusterin, and members of the cystatin protein super family such as histidine rich glycoprotein (HRG). The protein, comprises at least one of the following partial amino acid sequences: (a) glu thr tyr thr ser arg asn phe; (b) asp trp ser gly asp asp trp pro glu asp asp trp; Cc) arg ser gly val gly leu ser gln tyr gly trp ser; (d) trp ser ser asp lys lys asp glu thr glu asp lys thr; (e) gly thr gly tyr glu lys arg asp asp trp gly gly pro gly; (f) lys arg asp asp trp arg gly pro gly his ile pro lys pro. The protein and antibodies specific for the protein can be used in analytical procedures for determining the presence of virulent Streptococcus pyo genes in a sample. The protein can also be used in vaccine compositions.Type: GrantFiled: May 5, 2006Date of Patent: September 15, 2009Assignee: Genovis ABInventors: Per Åkesson, Lars H. Björck, Anders Sjohölm

Publication number: 20040091495Abstract: The present invention provides proteins and peptides derived from Streptococcus pneuminiae, type 3, which all the complement factor H (fH). These proteins and peptides show a homology of at least 50%, preferably at least 60%, and most preferably at least 70% with the subsequence from Thr38 to Lys 149 of the sequence disclosed herein as SEQ ID NO: 1. The above subsequence, which is located in the amino-terminal of a surface protein isolated from Streptococcus Pneuminiae, type 3, is highly associated with binding of fH. In another aspect, the invention relates to proteins and peptides showing a homology of at least 85%, preferably at least 95%, and most preferably at least 99% with the Hic protein, the amino acid sequence of which is disclosed is SEQ ID NO: 1. The invention also provides vaccine compositions comprising the above proteins and peptides.Type: ApplicationFiled: June 19, 2003Publication date: May 13, 2004Inventors: Lars Bjorck, Anders Sjoholm, Robert Janulczyk, Gianni Pozzi, Francesco Iannelli
