RESUMO

The remediation of the carbohydrate data of the Protein Data Bank (PDB) has brought numerous enhancements to the findability and interpretability of deposited glycan structures, yet crucial quality indicators are either missing or hard to find on the PDB pages. Without a way to access wider glycochemical context, problematic structures may be taken as fact by keen but inexperienced scientists. The Privateer software is a validation and analysis tool that provides access to a number of metrics and links to external experimental resources, allowing users to evaluate structures using carbohydrate-specific methods. Here, we present the Privateer database, a free resource that aims to complement the growing glycan content of the PDB.

RESUMO

Owing to the difficulties associated with working with carbohydrates, validating glycan 3D structures prior to deposition into the Protein Data Bank has become a staple of the structure-solution pipeline. The Privateer software provides integrative methods for the validation, analysis, refinement and graphical representation of 3D atomic structures of glycans, both as ligands and as protein modifiers. While Privateer is free software, it requires users to install any of the structural biology software suites that support it or to build it from source code. Here, the Privateer web app is presented, which is always up to date and available to be used online (https://privateer.york.ac.uk) without installation. This self-updating tool, which runs locally on the user's machine, will allow structural biologists to simply and quickly analyse carbohydrate ligands and protein glycosylation from a web browser whilst retaining all confidential information on their devices.

RESUMO

Passive transfer models were developed to evaluate the ability of antibodies generated in cynomolgus macaques and humans vaccinated with a recombinant plague vaccine (rF1V) to protect naïve Swiss Webster mice against pneumonic plague. Development of the passive transfer model is intended to support clinical and nonclinical development of the rF1V vaccine. To evaluate protection, unfractionated serum collected from rF1V vaccinated cynomolgus macaques and human volunteers with known antibody titers to rF1, rV and rF1V was transferred into naïve Swiss Webster mice via the intraperitoneal route. Results of these studies demonstrated that passive immunization protected mice from challenge or extended mean survival time and that the passive transfer assay can be used to evaluate the functional role of antibodies induced by rF1V vaccination in protection against aerosol exposure.
