Haem recognition by a Staphylococcus aureus NEAT domain.
Successful pathogenic organisms have developed mechanisms to thrive under extreme levels of iron restriction. Haem-iron represents the largest iron reservoir in the human body and is a significant source of iron for some bacterial pathogens. NEAT (NEAr Transporter) domains are found exclusively in a family of cell surface proteins in Gram-positive bacteria. Many NEAT domain-containing proteins,...
متن کاملSolution Structure and Molecular Determinants of Hemoglobin Binding of the First NEAT Domain of IsdB in Staphylococcus aureus
The human pathogen Staphylococcus aureus acquires heme iron from hemoglobin (Hb) via the action of a series of iron-regulated surface determinant (Isd) proteins. The cell wall anchored IsdB protein is recognized as the predominant Hb receptor, and is comprised of two NEAr transporter (NEAT) domains that act in concert to bind, extract, and transfer heme from Hb to downstream Isd proteins. Struc...
متن کاملRecognition of Staphylococcus aureus by the innate immune system.
The gram-positive bacterium Staphylococcus aureus is a major pathogen responsible for a variety of diseases ranging from minor skin infections to life-threatening conditions such as sepsis. Cell wall-associated and secreted proteins (e.g., protein A, hemolysins, and phenol-soluble modulin) and cell wall components (e.g., peptidoglycan and alanylated lipoteichoic acid) have been shown to be infl...
متن کاملRapid Detection of Vibrio Cholera by a Coagglutination Complex using Staphylococcus aureus Including Protein A
Introduction: Vibrio cholera is a gram-negative bacterium that causes cholera which is an acute diarrheal illness. Cholera outbreak mostly happens in hot seasons when the bacteria reproduce rapidly in water contaminated with feces. Severe diarrhea and mortality have been the prevalent symptoms of cholera which affect the hygienic status and economic features of humans during centuries. There is...
متن کاملPrevalence of clindamycin-resistant Staphylococcus aureus induced by macrolide resistance
Introduction: Since the incidence of various infections caused by Staphylococcus aureus increases, the use of effective antibiotics such as clindamycin has been growing to treat the systemic and local infections caused by such organisms. Antibiotic-resistant species are emerging and spreading in today's communities due to misuse of antibiotics and incomplete treatment, turning into a serious ch...
