The multifunctional Staphylococcus aureus autolysin aaa mediates adherence to immobilized fibrinogen and fibronectin.
Staphylococci can cause a wide spectrum of infections, including endocarditis, osteomyelitis, and sepsis, which is reflected by the numerous virulence factors they produce, among them a recently identified new class of adhesins, namely, the multifunctional autolysins/adhesins. Here we report the identification and molecular characterization of Aaa, a novel autolysin/adhesin from Staphylococcus ...
متن کاملAn autolysin ring associated with cell separation of Staphylococcus aureus.
atl is a newly discovered autolysin gene in Staphylococcus aureus. The gene product, ATL, is a unique, bifunctional protein that has an amidase domain and a glucosaminidase domain. It undergoes proteolytic processing to generate two extracellular peptidoglycan hydrolases, a 59-kDa endo-beta-N-acetylglucosaminidase and a 62-kDa N-acetylmuramyl-L-alanine amidase. It has been suggested that these ...
متن کاملAdaptation in a Fibronectin Binding Autolysin of Staphylococcus saprophyticus
Human-pathogenic bacteria are found in a variety of niches, including free-living, zoonotic, and microbiome environments. Identifying bacterial adaptations that enable invasive disease is an important means of gaining insight into the molecular basis of pathogenesis and understanding pathogen emergence. Staphylococcus saprophyticus, a leading cause of urinary tract infections, can be found in t...
متن کاملEvaluation of humoral and cellular immunity of recombinant autolysin protein Staphylococcus aureus in mouse model
Background: Staphylococcal aureus is a gram positive cocci and opportunistic pathogen. Due to the spread of this bacterium to antibiotics resistance, one of the most important ways of prevention is the use of vaccines. In this respect, autolysin protein as one of the adhesion molecule of bacteria plays an important role for binding bacteria to the host cells and cell division. Herein, the role ...
متن کاملFibronectin-mediated Uptake of Gelatin-coated Latex
The present study demonstrates the ability of plasma fibronectin or cold-insoluble globulin (CIg) to promote the uptake of ' 251-labeled, gelatin-coated latex beads (g-Ltx*) by monolayers of peritoneal macrophages (PM) . The uptake of g-Ltx* by PM was enhanced by CIg in a concentration-dependent fashion and required the presence of heparin (10 U/ml) as an obligatory cofactor for maximal particl...
