I have a large molecule to refine.There are about three thousand residues in one asymmetric unit. Except for the lack of electron densities in several places, where the loops have been deleted, the rest parts fits well with density. But the R free and R work are all beyond 0.30 (R free =

Re: [ccp4bb] How to refine large moleculars?

2008-01-07 Thread Tim Gruene
Depending on your data quality and the nature of the crystal it might be that you cannot reduce R/Rfree any further. Low R/Rfree is not the goal of refinement and model building - at least not for the humans doing it. The goal is to get as good a model as possible, and if your data are not very

Re: [ccp4bb] how to model this density?

2008-01-07 Thread Artem Evdokimov
You should check if this residue is a part of a glycosylation pattern (either via crude computational sequence analysis, or if you're lucky - by digest and peptide MS). The density *looks like* a disordered sugar but at 2.6A this is a very tough call. Artem _ From: CCP4 bulletin
