THe BuScr allows you to predict the three-dimensional structure of a triple-helical collagen molecule with the primary sequence of your choice. You have the ability:

    1. to tweak the manner in which the helical structure is assigned;

    2. to visualize triple-helix stability in terms of predicted local melting temperatures;

    3. to fully customize the open source Tcl/Tk script (GNU licensed);

    4. to fully customize the helical parameters and stability measures.

    5a. to predict all-atom Pro/Hyp (+ Ala) side-chains and interface this with SCWRL for remaining side-chain prediction.

    5b. or, to include side-chain terminal atom predictions. Uses method developed in: Rainey and Goh (2004), J Chem Inf Comput Sci, 44: 817-830.
Paper (521 kB PDF). And supplementary material (1.3 MB PDF.)


ver. 1.07a released - July 2021 (changes to documentation and HypScwrl3.tcl but not to main THeBuScr script)

ver. 1.07 released - June 2013

ver. 1.06 released - Oct. 2008

ver 1.05 finally released (Dec. 2006).

New host site at Dalhousie University (Nov. 2006).
To run THeBuScr you will need Tcl/Tk. We chose this freeware multi-platform scripting language due to its graphical interface capabilities independent of platform, the ease with which it allows file handling and management, and its ready customizability.
