Re: [ccp4bb] Same protein showing different SG

Dear Dipankar, To me, it looks like you have a (slight) problem with your goniometer/detektor in that e.g. the rotation axis is not exactly horizontal/vertical/perpendicular to the beam, or that the detector parameters (especially when using a swing-out) were not completely correctly refined

[ccp4bb] Fitting of a trigonal bipyrimidal phosphorus

Dear all, Could anybody please tell me how to get the coordinate file and the cif file for the trigonal bipyramidal (TBP) phosphorus (figure given below for your convenience)? Prodrg server is not helping out in this issue. Thanks in advance. Regards, Sudipta. Sudipta Bhattacharyya Senior

Dear Sudipta, Use Phenix eLBOW. Give the input SMILES string and get the pdb and cif restraint files as output. Also you can use http://cactus.nci.nih.gov/translate/ to first get the pdb coordinate file from the SMILES string and then run Phenix eLBOW to get the cif restraints. Best regards,

Wouldn't bacteriorhodopsin be a good choice, especially since it's colored and easy to express? Seems pretty expensive for a class, though, with all the detergents involved... JPK On Tue, Sep 11, 2012 at 4:18 PM, Ho Leung Ng h...@hawaii.edu wrote: Hello, I am developing an

Two additional suggestions: 1. Photosynthetic Reaction Center from *R. sphaeroides* might be up your alley. Similar to bacteriorhodopsin, no need for a GFP tag on this one as it's colored. See the following publications: Wallace et al. Monoolein Lipid phases as incorporation and inrichment

Hi, Just for info if you were to use the LCP method (a course by itself), check this about OmpF (membrane lysozyme): http://www.sciencedirect.com/science/article/pii/S1047847712000834 bR protein sometimes takes weeks to give crystals and people prefer the dark (depends on the conf state).. but

The multidrug efflux transporter AcrB could be suitable including crystallization (both recombinant with His-tag and endogenous). Extracts, solubilizes, purifies and crystallizes in DDM, so it is fairly inexpensive to repeat in bulk compared to other detergents. Assays might be a bit
