[SA_scat] Small Angle Scattering Biological Data Bank,www.sasbdb.org

Dear Colleagues,

we are very pleased to  announce the launching of the Small Angle Scattering
Biological Data Bank (SASBDB, www.sasbdb.org <http://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 an
on-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
