Aminoacyl-tRNA synthetases (AARSs) are a structurally heterogeneous family of enzymes present in prokaryotes, archaea and eukaryotes. They catalyze the attachment of tRNA to its corresponding amino acid via an aminoacyl adenylate intermediate. Errors in protein synthesis will occur if an
The influenza virus hemagglutinin (HA) fusion protein has long been viewed as a "spring-loaded" fusion machine whereby activation at low pH initiates a rapid and irreversible cascade of conformational changes that drives the membrane fusion reaction. This mechanism has shaped

D and L isomers of aspartic acid beta-hydroxamate (respectively DAH and LAH) were compared for their in vitro and in vivo activity against the murine leukemia L5178Y and their tolerance in vivo in DBA/2 mice. DAH and LAH displayed comparable

Bacteria within Curli biofilms are protected from environmental pressures (e.g., disinfectants, antibiotics), and this is responsible for intractable infections. Understanding aggregation of the major protein component of Curli, CsgA, may uncover disease-associated amyloidogenesis mechanisms. Here, we report the application of
Mutations in the ubiquitin ligase parkin are responsible for a familial form of Parkinson's disease. Parkin and the PINK1 kinase regulate a quality-control system for mitochondria. PINK1 phosphorylates ubiquitin on the outer membrane of damaged mitochondria, thus leading to recruitment
