A partial mirror containing the reference sequences for the human, mouse, rat, and other vertebrate (and one insect) genomes, as well as tools for display and analysis.
EyeBrowse [Web]
This site displays expressed sequence tag (EST) cDNA clones from eye tissues (derived from NEIBank and other sources) aligned with current versions of the human, rhesus, mouse, rat, dog, cow, chicken, or zebrafish genomes, including reference sequences for known genes. This gives a simplified view of gene expression activity from different parts of the eye across the genome.
Protein Data Bank [Helix/Biowulf] [NFS-mountable]
The Helix Systems maintains a mirror of the Protein Data Bank entries, which can be accessed in the /pdb area on Helix, the Biowulf head node, or the Biowulf computational nodes.
The PDB mirror can also be NFS-mounted by any Unix system at NIH. To access this mirror via NFS, system administrators should add the following entry to /etc/fstab on your Unix desktop system:
helixdb.nih.gov:/vol/pdb /pdb nfs ro
Type mkdir /pdb, and then mount -a to complete the mount. Contact staff@helix.nih.gov with any questions.
Cambridge Structural Database System (CSDS) [Helix]
The Cambridge Structural Database System (CSDS) consists of two major components:
The Cambridge Structural Database (CSD)
Bibliographic, 2D chemical and 3D structural results from crystallographic analyses of organics, organometallics and metal complexes. Both X-ray and neutron diffraction studies are included for compounds containing up to ca. 500 atoms (including hydrogens).
Software for Search, Retrieval, Analysis and Display of CSD contents
Comprised of the programs QUEST/QUEST3D (for text, numeric, 2D substructure and 3D geometric searching), VISTA (for 3D analysis of QUEST3D searches), GSTAT (for 3D search and data analysis) and PLUTO (graphical display of 3D structures).
Other databases
The helix systems group also maintains a list of databases available elsewhere on the web.
