Activity of the major staphylococcal autolysin Atl.
The major autolysin of Staphylococcus aureus (AtlA) and of Staphylococcus epidermidis (AtlE) are well-studied enzymes. Here we created an atlA deletion mutant in S. aureus that formed large cell clusters and was biofilm-negative. In electron micrographs, the mutant cells were distinguished by rough outer cell surface. The mutant could be complemented using the atlE gene from S. epidermidis. To ...
متن کاملNovel hacksaw-like structure of the autolysin inhibitor IseA
Background: IseA from Bacillus subtilis is an inhibitor protein against DL-endopeptidases including synthetic lethal autolysins. Results: We solved the solution structure of IseA using NMR. Titration with LytF DL-endopeptidase indicated interaction sites around the loop region. Conclusion: The IseA structure revealed a novel “hacksaw”-like fold with a characteristic inhibitory loop. Significanc...
متن کاملCloning of Minor Autolysin of Streptococcus Pneumoniae
Abstract Background and Objective: Increased antibiotic resistant strains and inadequacy of current vaccines against pneumococcal infections necessitate the study of novel protein antigens. It seems that minor autolysin of Streptococcus pneumoniae may have antigenicity. Thus, we aimed at cloning its gene for the first time. Material and Methods: After DNA extraction of Streptococcus pneumoniae ...
متن کاملMobile advertising: The changing landscape of the advertising industry
As mobile technologies continued to advance, a new platform of advertising known as mobile advertising (m-advertising) has emerged. This study explores factors that influence consumers’ behavioral intention (BI) to use m-advertising by proposing an extension of Unified Theory of Acceptance and Use of Technology (UTAUT) model with personal innovativeness in information technology (PIIT), perceiv...
