Dear Colleagues,
we are very pleased to announce the launching of the Small Angle
Scattering Biological Data Bank (SASBDB, www.sasbdb.org).
SASBDB was developed in accordance with the plans of the wwPDB SAS task
force to establish a federated system of
interconnected databases for X-ray and neutron scattering (SAXS/SANS).
SASBDB is a curated repository that makes experimental SAS data and
derived models of biological macromolecules
discoverable, citable and downloadable. Within SASBDB, it is possible to
browse the scattering data and models,
search by various keywords including macromolecule name, buffer
composition, experiment setup and author/affiliation
details. 3D representations of low resolution ab initio bead models and
of the hybrid rigid body models
are available. All data sets and models can be freely downloaded.
Presently, SASBDB comprises of 96 experimental data sets and 151 models.
Most of the entries contain published data from the studies
where SAS was used for the structural analysis of macromolecular
solutions (proteins, nucleic acids and complexes). There
are also several "benchmark" data from a set of well-characterized
commercially available proteins. The SAXS (and, for some
proteins, also wide-angle scattering, WAXS) data from these samples were
collected using an on-line purification system to ensure
sample monodispersity. The benchmark set data and models can be used to
test computational approaches, for tutorials etc.
Researchers are welcome to deposit the SAXS/SANS data and models into
SASBDB (prior to or after the publication).
The submission requires a simple sign-in procedure followed by filling
in anon-line deposition form and uploading the data/models.
ATSAS and ATSAS-online users may directly use their credentials to sign in.
The deposition is pre-moderated, i.e. the entries will be validated
before making them public.
ATSAS Team, EMBL-Hamburg
