Nigel, crazy thing, I repeated the ELBOW run with the exact same smiles for: 1.10-2155 and 1.10.1-2155 and it gives different results. With the newer version addressing the sugar correctly, as you said. Thanks! André André C.

postdoctoral position MRC Laboratory of Molecular Biology
by Roger Williams 26 Jan '16

26 Jan '16

A three-year postdoctoral position is available with the group of Roger Williams at the MRC Laboratory of Molecular Biology in Cambridge, UK. The project, which is funded by Cancer Research UK is aimed at understanding structural mechanisms of regulation of the target of rapamycin complexes. Specifically to undertake research to investigate the structures and regulation of the mTORC1 complex assembled with its regulators on lysosomal membranes. The objective is to determine the structures of mTORC1 in complexes with its regulators and to understand how these complexes assemble on lysosomal membranes. Methods involved in the study include large scale mammalian cell culture, cryo-electron microscopy; X-ray crystallography; hydrogen-deuterium exchange mass spectrometry; biophysical measurements of assembly on membranes by confocal microscopy, flow cytometry and single-molecule fluorescence; and enzyme assays. The candidate should have a Ph.D. degree or due to complete doctoral studies within 6 months of applying. It is essential that the candidate has an enthusiasm for structural biology. Experience with electron microscopy, X-ray crystallography, mass spectrometry or large scale eukaryotic expression systems would be desirable, but a motivated candidate could learn any or all of these. The MRC Laboratory of Molecular Biology is one of the birthplaces of modern molecular biology and has amazing support for all aspects of structural biology.

Modify methionine to acetylated methionine in coot
by Anshul Bhardwaj 25 Jan '16

25 Jan '16

Hello, How to replace 'M' with 'AME' in coot itself? an option like mutate residue, etc. I couldn't figure out right away so I worked my way around by simply copying AME from one of the pdb from RCSB database and replaced methionine in my model. Linked AME to residue# 2 in coot and refinement was straightforward after generating restraints for the modified model. So it worked for now but still curious as there has to be a way to replace 'M' with 'AME' in coot, isn't it (?). Thanks, Anshul Bhardwaj P.S. Hope it's okay to cross-post on both ccp4bb and phenixbb to get an answer quickly. The information contained in this transmission contains privileged and confidential information.

Coot 3D for Geforce GTX 970 Graphics card on Windows 7 and Fedora
by Xiao Lei 25 Jan '16

25 Jan '16

Hi Phenixbb members, My lab has a desktop PC which has Windows 7 with Geforce GTX 970 Graphics card, is this card ok for the Coot 3D function with 3D monitor and Nvidia 3D kit? Do I need to do some settings before I can use the Coot 3D function? I'm also thinking installing Fedora 23 on the PC and use coot 3D, is there any settings in the Fedora environment before using coot 3D? Thanks ahead.
