The First African Structural Biology Conference Macromolecular Structure, Health and Biotechnology in Developing Countries The Wilderness, South Africa 24-27 October 2006 The First African Structural Biology (FASB) conference will be held in The Wilderness, South Africa. The conference will focus on the contributions and potential contributions of Structural Biology to the development of science and the creation of wealth in Africa with some emphasis on biotechnology and the alleviation of the disease burden of Africa. In particular, the conference has the following aims: 1. To promote structural biology in Africa, particularly in South Africa 2. To discuss contributions to the relief of disease, especially, TB, AIDS and malaria that have been made through an understanding of macromolecular structure 3. To provide the opportunity for South African students and scientists to meet and interact with some of the leading Structural Biologists in several fields that are relevant to our continent 4. To explore the merit and practicality of studying macromolecular structure in Africa 5. To discuss strategic and funding policies for structural biology and benchmark South Africa against other developing countries, notably Brazil and India 6. To identify projects of interest to the South African community in which structural analysis could play a role. The early registration deadline is 1 May 2006. Abstracts are due on 31 August 2006 Expression of interest and registration forms can be submitted online by visiting our website: http://sbio.uct.ac.za/conference Plenary lecturers: Tom Blundell (http://www-cryst.bioc.cam.ac.uk/~tom/) M.

Good Day!!!!!!!!! I had installed modeller software in my computer. I was practising the basic commands. I am comfortable till executing the command. $mod8v2 Target_profile.py Execution was successful and I got the information for Target_profile.log and Target_profile.prf as described in the tutorial. But to the next step when i run the command $mod8v2 Target_compare.py i get these errors!!!!!!!!!!!! ============================================================================= Traceback (most recent call last): File "Target_compare.py", line 7, in ? aln.malign3d() File "/usr/lib/modeller8v2/modlib/modeller/alignment.py", line 210, in malign3d io=io.modpt, libs=libs.modpt, **vars) File "/usr/lib/modeller8v2/modlib/modeller/util/top.py", line 93, in malign3d return _modeller.malign3d(aln, io, libs, *args) _modeller.error: malign3_682E> Structural information is not available for all sequences in the alignment. Aborting. ============================================================================ I have downloaded the necessary PDB files manually, Could you tell which/where directory to paste these files with a detailed command list since i am beginner to modeller. With Regards Robert Selwyne.

Modelling of the interface of a protein complex
by Karsten SUHRE 27 Apr '06

27 Apr '06

Dear Modeller users, To study the interface between two proteins in complex (A+B), i.e. to decide whether these proteins may form a complex, I wish to compute a homology model on the basis of an existing, but only remotely homologous, complex (A'+B'), i.e. there are difference in some indels close to the interface. Each of the target proteins has also a closely homologous template, (A" and B"), which I would like to use to model the indels. However, as I am particularly interested in the interface, it is crucial to model the sidechains at the interface correctly, that is to account for the presence of the binding partner. Thus, the remote homologue (A+B) bears some important information as what concerns the complex. The most direct approach would be to use all templates and let MODELLER decide what to do. But is this really the optimal approach? Thank you very much in advance for any suggestion, or reference to similar problems. Kind regards, Karsten.

Problem with evaluate_model.py

Dear users, I am trying to obtain the DOPE potential and the corresponding plot for my best model. I am using the evalute_model.py script from the web tutorial, but when I run it I get this error: Traceback (most recent call last): File "evaluate_model.py", line 24, in ? normalize_profile=True, smoothing_window=15) TypeError: assess_dope() got an unexpected keyword argument 'output' Can somebody help me?. Thanks a lot in advance.

Concatenating models
by Alex Brown 24 Apr '06

24 Apr '06

Hi. A simple question - is it possible to concatenate (add) two models, using a MODELLER script, to create a single file ? I know that two files can be added together using Unix commands or using a text editor, but then the atom numbers are duplicated (I'm not sure this is a problem tho'). Cheers, Alex Brown
