CCL:heparin

[mjf(-(at)-)biosym.com (Mark J Forster )]

 Dr David Devan asked for information and coordinates for
 anionic polysaccharides specifically heparin.
 Dr Barbara Mulloy (bmulloy(-(at)-)nibsc.ac.uk) and myself
 (mjf(-(at)-)biosym.com)
 have recently deposited coordinates of NMR structures of heparin
 in which the IdoA ring adopts either the 1C4 or 2S0 forms. The
 coordinates should be available from the Brookhaven PDB as entry 1HPN.
 Please see the references
 B. Mulloy, M. J. Forster, C. Jones and D. B. Davies, "NMR and
 molecular-modelling studies of the solution conformation of heparin"
 Biochem. J. 293 (1993) 849-858.
 Hope this helps.
 Best Wishes.
