| Supplied Information: |
Chemscape Chime, a Web browser plug-in that can display 2D and 3D structures embedded within an HTML page or table. Chime displays structures directly within an HTML page, rather than through a helper application in a separate window. It displays structures directly within an HTML table, to allow for multiple structures within an HTML page. It supports MDL Molfile, MDL Rxnfile, Brookhaven Protein Databank (PDB), Minnesota Supercomputer Center's (MSC) XMol XYZ, Gaussian Input, IEMBL Nucleotide Format, RasMol Script File, Mopac Input File, and Chemical Structure Markup Language File. Structures within the plug-in are "live"; they can be rotated within the plug-in in real time. The user has interactive control over the display (eg ball-and-stick, protein backbone, rotation, colour etc.). |
| Possible Use: |
This product is suitable for First Year Tertiary / Second Year Tertiary / Third Year Tertiary courses for use by students without supervision. |
| Review: |
ChemScape Chime is a WWW browser plug-in module, which converts various chemical data files into a 3-dimensional image of a molecule , nucleic acid, or protein. It is based on the RasMol software developed by Roger Sayle, but specially adapted for use with WWW-based chemical images, and with fewer features than RasMol [ftp://ftp.dcs.ed.ac.uk/pub/rasmol/]. Chime is provided by MDL Information systems [http://www.mdli.com/chemscape/chime] free for all users, subject to the licence agreement.
By clicking anywhere on the image, the user can interactively change the view from (eg) a ball-and-stick structure to space-filling, wire frame, protein-ribbon or other models. There is also interactive control of rotations, colour, etc. By manipulating the image, the user can gain an appreciation of the 3-dimensional structure of the molecule or protein. The menu also allows the user to download the original data file or to copy the image to another file.
Many university departments within Australia and overseas have already adopted Chime to support WWW-based teaching materials. The author of the WWW page embeds the Chime image:
<EMBED SRC="1d66.pdb" WIDTH="264" HEIGHT="400" spiny="180" startspin="true" spinfps="15" display3D="strand" color3D="temperature">
In this example, the original data is a Protein Data Bank (.pdb) file, and the options will display the protein backbone as strands which are rotating about the (vertical) y-axis. Other types of data files are also supported: eg MDL (.mol files), XMol animations (.xyz files). Chime supports many (if not most) of the IUPAC-recognised Chemical MIME types [Rzepa, Rust, Whitaker, Chemistry International, 1997, 19(1), 17; http://www.ch.ic.ac.uk/chemime/iupac.html]. There are extensive WWW-based tutorials available for the new Chime author [see links at http://www.mdli.com/chemscape/chime/sampidx.html]. |
