[Question from NMRWiki Q&A forum] shake routine and ncon parameter
shake routine and ncon parameter
Trying to do molecular dynamics with explicit water molecules I came across a problem with SHAKE routine:
shake reference = parameters bonds (hydrogen) (all) tolerance = 1.0e-06 nconstraints=8000end
and error message after this is:
X-PLOR>shake SHAKE> reference = parameters SHAKE> bonds (hydrogen) (all) SELRPN: 7142 atoms have been selected out of 11032 SELRPN: 11032 atoms have been selected out of 11032 SHKSET: reference = parameters %XREFIN-ERR: allocation for SHAKE-constraints exceeded ...

[NMR software blog] Routine Prediction
Routine Prediction
Not everybody remembers how easy it is and how effective it can be to add (or correct) a few points at the beginning of the FID. Two years ago I explained how Linear Prediction works and how we can extrapolate the FID in both directions. This time I will show a simple practical application.
I have observed that, in recent years, C-13 spectra acquired on Varian instruments require a much-larger-then-it-used-to-be phase correction. When I say correction, I mean first-order phase correction, because the zero-order correction is merely a different way of representing the...

Structure determination of protein?RNA complexes in solution provides unique insights into factors that are involved in protein/RNA recognition. Here, we review the methodology used in our laboratory to overcome the challenges of protein?RNA structure determination by nuclear magnetic resonance (NMR). We use as two examples complexes recently...

This chapter describes nuclear magnetic resonance (NMR) methods that can be used to determine the structures of protein complexes. Many of these techniques are also applicable to other systems (e.g., protein-nucleic acid complexes). In the first section, we discuss methodologies for optimizing the sample conditions for...

Introduction
As the structures of more proteins and domains are solved by structural genomics projects, the future of structural biology will be oriented more toward the study of macromolecular complexes. Since so many biological processes are mediated by interactions between proteins, it is important to study them at a molecular level. The study of protein-protein interactions also has applications in a...
