OMEGA is a compilation of recent structural information on
proteins derived from X-ray crystallography or NMR and
published in journals referenced by Current Contents.
To date, 401 entries have been included ( 334 X-ray, 28 NMR,
5 NMR + X-ray, 5 electron microscopy, 3 neutron scattering,
2 neutron diffraction, 1 electron microscopy + X-ray,
12 model, 11 miscellaneous ), with 5-10 new proteins being
added each week.
OMEGA can be accessed on Macintosh and is interrogated
through 32 key words (space group, resolution, secondary
structure, number of residues, etc). This pool of proteins
could be used for various purposes, including searches for
proteins with a particular set of secondary structures.
OMEGA will be continuously updated (every 6 months) and
may later include all proteins already reported in the PDB,
as well as structures reported in journals with smaller
We would greatly appreciate any ideas for improving future
releases. We also apologize in advance for any errors or
omissions that may appear in the database, and would be
grateful to be informed of any errors.
We also welcome submission for entry in OMEGA of any new
publication related to the determination of a protein
structure, as well as the citing of this paper as a
reference for the OMEGA databank.
We would appreciate receiving reprints of publications
making use of OMEGA.
