      <i>Staphylococcus aureus</i> is known as a frequent colonizer of the skin and mucosa. Among bacterial factors involved in colonization are adhesins such as the microbial surface components recognizing adhesive matrix molecules (MSCRAMMs). Serine aspartate repeat containing protein D (SdrD) is involved in adhesion to human squamous cells isolated from the nose. Here, we identify Desmoglein 1 ...

      The recently discovered lytic polysaccharide monooxygenases (LPMOs), which cleave polysaccharides by oxidation, have been associated with bacterial virulence, but supporting functional data is scarce. Here we show that CbpD, the LPMO of <i>Pseudomonas aeruginosa</i>, is a chitin-oxidizing virulence factor that promotes survival of the bacterium in human blood. The catalytic activity of CbpD was ...
    • Serine-aspartate-repeat protein D Increases Staphylococcus aureus Virulence and Survival in Blood 

      Askarian, Fatemeh; Uchiyama, Satoshi; Valderrama, J. Andrés; Ajayi, Clement; Sollid, Johanna U. E.; Van Sorge, Nina M.; Nizet, Victor; van strijp, Jos A. G.; Johannessen, Mona (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-10-17)
      Staphylococcus aureus expresses a panel of cell wall-anchored adhesins, including proteins belonging to the microbial surface components recognizing adhesive matrix molecule (MSCRAMM) family, exemplified by the serine-aspartate repeat protein D (SdrD), which serve key roles in colonization and infection. Deletion of sdrD from S. aureus subsp. aureus strain NCTC8325-4 attenuated bacterial survival ...
