Hi all, I have been attempting to find a MR solution for a low resolution data set (3.9A), with pretty poor merging stats of a 22 strand membrane beta barrel I'm working on.
I've created a trimmed poly-alanine from a structure of 17% identity, that gives a solution with a Tfz of 14.3 with two molecules per asu (llg is around 900). I'm guessing this in a genuine solution, but the map is too poor to build into. Does anyone have any advice as to proceed from here? It may be just a case of needing better resolution data to work with, but would this indicate that Selenomet derivative crystals won't be needed for this structure? Cheers, Rhys
