Modeling Disordered Domains
by Damian Ekiert 06 Apr '11

06 Apr '11

Perhaps inspired by the fierce debate on this BB and elsewhere about how to model disordered side chains, I would like to present the following scenario (my current refinement project): The structure was solved by molecular replacement, is 3.25Å resolution, and ~70% solvent. I have 6 copies of a large complex in the AU (~100kDa per protomer). Only one copy is fully ordered. In the other 5 copies, a entire domain (~25kDa) is largely disordered (some have patchy residual density, but not readily interpretable). Altogether, this means that I am missing ~20% of the total protein in the AU. It seems that how you model this much "missing" material could have a significant effect on the final refined model. This is something we have observed a number of times, so I am wondering if anyone can suggest ways to deal with this aside from just leaving the domains out entirely. In this case, the missing domain is connected by two short hinges that restrict the rotational degrees of freedom considerably (you can think of the missing domains as a door--it can only pivot about the hinge, can't be flipped upside-down or sideways, etc., and is anchored close to the door frame). Additionally, crystal packing and steric constraints restrict the "sweep" of the missing domains to further pinpoint their location. Is it worth trying to model this? My impression from some earlier posts was that most people were content for disordered regions to be modeled as bulk solvent (rather than fiddling with masks to also cover the expected location of protein, etc.), but I wonder if you may actually substantially improve the model when this much protein is disordered. I guess I am imagining something analogous to a rigid body fit to the mean position of the disordered domains and a TLS-like ADP description of the motion (with a very large magnitude to account for the large displacement), but I am open to suggestions. On a final note, regarding those pesky missing side chains: any thoughts on trying to employ a "Ringer"-like approach to model some of these (Fraser, et al., Nature 2009, 462(7273):669-673)? Is this practical (maybe this would add to many additional parameters)? Best, Damian Ekiert

Re: [phenixbb] occupancy on a special position
by Maia Cherney 06 Apr '11

06 Apr '11

Hi, I have a water on a two fold axis, I gave it occupancy 0.50, but the program makes it 1.0. I know this was discussed before, but we have to abide by the PDB rules, that is to have this occupancy =0.5. Could you please, fix this problem. Maia

Mainly doing rigid body refinement of various pieces and individual xyz for a few select loops, but NOT refining ADP. Yes, The B-factors are all exactly the same. So I guess this represents the overall B correction. Thanks, Scott

Mac 64-bit kernel
by Joseph Noel 05 Apr '11

05 Apr '11

Nope. I've set up to always run the 64-bit kernel. I am a bit of a Mac lover so go pretty in depth with the operating system. I think Nat fixed things. For the last many latest builds, I have always installed from the source files for linux/mac to ensure I am running at maximum memory capacity. ___________________________________________________________ Joseph P.

latest 64-bit command line build for Mac OSX 10.6.7?

Hi, I was trying to install the latest nightly build but get error (shown after my salutation) when using the recommended procedure: ./install --prefix=/Applications/ Previously, I always installed from source so I could run the 64-bit version on Mac since I have some structures that require as much memory as possible. Should I just go back to that? It does take about an hour to install on my laptop. I assume this latest 64-bit option would significantly reduce the time for installation since I wouldn't be compiling from the source. Cheers!

Minor map-definition bug in 1.7 GUI
by Joe Krahn 05 Apr '11

05 Apr '11

The new GUI has "---" in the list of map types for phenix.refine. Users expect this to mean "don't use map definition". I think there was previously a blank menu entry that worked this way. Instead, it is written to the .def file, and the job gives an error, but otherwise works OK. Thanks, Joe Krahn
