A WWW sewer is described for creating 3D models of canonical or bent DNA st
arting from sequence data. Predicted DNA trajectory is first computed based
on a choice of di- and tri-nucleotide models (M.G.Munteanu et al., Trends
Biochem. Sci. 23, 341-347, 1998); an atomic model is then constructed and o
ptionally energy-minimized with constrained molecular dynamics. The data ar
e presented as a standard PDB file, directly viewable on the user's PC usin
g any molecule manipulation program.
