A half century of structural studies have shown the design principles controlling self-assembly of viral proteins into icosahedral virus capsids. A large repertoire of virus structures, mainly determined using X-ray crystallography and cryo-electron microscopy, are now conveniently available and carefully … Continue reading
Researchers have used hybrid structural approaches to construct a pseudo-atomic model of a calicivirus. Continue reading
Human adenoviruses (HAdV) are non-enveloped double-stranded DNA (dsDNA) viruses associated with acute infections. Although these infections are generally self-limiting, the re-emergence of certain HAdV types has also been linked to potentially fatal respiratory infections in both civilian and military populations. … Continue reading
Most viruses are either helical or icosahedral in structure. The two highly symmetric shapes permit viruses to use the same component protein multiple times to create large structures from a minimum number of distinct protein species. The strategy conserves the … Continue reading
Chemoreceptors are key components of the high-performance signal transduction system that controls bacterial chemotaxis. Chemoreceptors are typically localized in a cluster at the cell pole, where interactions among the receptors in the cluster are thought to contribute to the high … Continue reading
