[ccp4bb] Wyatt DynaPro Titan and Dynamics

2014-06-26 Thread Brent B. Crow, Ph.D.
Hello all, I am currently running a Wyatt DynaPro Titan DLS using Dynamics 6.7.7.1.  Ten days ago, the hard drive on the XP computer running the instrument totally failed and can no longer be accessed.  I replaced it with a clone and tried to reconnect the Titan, but the two drivers needed by t

[ccp4bb] How to remove phospholipids bound to a cytoplasmic protein

2014-06-26 Thread Lionel
Dear all, I would like to remove two phospholipids bound to (actually into) a cytoplasmic protein. The protein was expressed in E. coli and the crystal structure revealed the presence of two co-purified phospholipids (most probably DPPE). A web search gave me three methods to remove bound lipi

Hi Lionel, A few musings/suggestions If they are bound *inside* the protein, this suggests that the phospholipids might be very tightly bound. Do you have an affinity tag on your protein (e.g. His tag)? Perhaps you might immobilise the protein on a suitable resin and wash with copious amounts of

Dear CCP4BBers: I'e got a problem about data processing when running SCALEPACK2mtz. Hope you can give me some advice on that. Here's my problem: I have an .sca file processed by HKL2000 about 4 years ago, I just ran the Scalepack2mtz program in order to transform it into .mtz file. However, the

Hi Jeff, You can compare volume of binding cavities of two proteins. You can quickly check cavity size in your structure using PDBsum or you can use a program called viodoo to calculate volume of the cavity. Following paer can be helpful http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2683046/ Rega
