Desktop Molecular Modeller

The latest version of this popular molecular modelling program runs in Windows, and takes full advantage of SVGA graphics and the 256 colours available in this environment to enhance the representation of models on screen. There are many new features, including enhanced modelling and energy minimization facilities and improved display styles, using algorithms unique to DTMM. There are five structure libraries, comprising over 400 structures, available for use with the main modelling program. New Features: BLdocking of multiple structures BLsuperposition BLgraphical display of energy terms during minimization, including bond, angle, torsion, Van der Waals, and electrostatic energies. BLcalculation of volume and surface area. BLpeptide build facility for constructing peptides from their constituent amino acids with the preferred geometry (choose from right-handed alpha, 3(10), or pi-helix, parallel or antiparallel sheet). BLdisplay of secondary structural elements of proteins: helices as cylinders and sheets as large solid arrows.
BLthree new display styles: charge distribution at the van der Waals radius, space fill with light-source shading or shading used to represent electrostatic potential. (The last two use 256 colours on appropriate graphical displays.) BLfuse ring command and facility for changing the chirality of stereoisomers BLannotation of any display with text and arrows.
