---- ATTENTION ALL PROTEIN MODELLERS ----

NEW DRAGON RELEASE, ** AND ** SAP STRUCTURE COMPARISON 
                               PROGRAM NOW AVAILABLE
                    
DRAGON Version 4.17.7 is now available in SGI executable format
at the following site:-
http://www.nimr.mrc.ac.uk/~mathbio/a-aszodi/dragon.html
This is a minor update to the previous version (4.17.6)
containing the following changes:-

- OpenGL graphics is now supported in all three DRAGON executable
formats;
- an output file directory may be specified which will be
  created by the program if it does not exist already;
- a few default parameter values have been changed;
- the distributions now include the CLUMSY program
  for clustering the structures produced by DRAGON;
- the N64 executables are tuned to the R10000 processor instead of the
R8000.

DRAGON is a protein modelling tool using Distance Geometry.
It was developed at the Division of Mathematical Biology of
the National Institute for Medical Research in London
between 1993 and 1996. DRAGON attempts to predict
the tertiary structure of a small soluble protein, given
its sequence, the secondary structure and possibly a set of
interresidue distance restraints. If the structures of
some of the sequences in the multiple alignment is known,
then you can attempt comparative modelling. DRAGON communicates
with you through a simple command-line interface which is used
to specify parameter values and input filenames.

SAP can be found at:
ftp://glycine.nimr.mrc.ac.uk/pub/sap/
or links from a collection of protein links:
http://www.nimr.mrc.ac.uk/~mathbio/r-munro/prot-link.html

SAP is an updated program for the comparison of 2 protein structures
(first implemented as SSAP) by Taylor and Orengo (1989).  SAP returns a
superposition of the 2 proteins in PDB format as well as printing the
alignment information, score and RMSd's for the protein.  A fast
protein visualization tool (PROTDRAW) is also included for viewing
proteins.  
Have fun,
Robin Munro.
