CCP4bb navigationCCP4bb <-- 1999 <-- November 1999 <-- 30 November 1999Subject: refinement problem of labelled RNA complex From: ºîº£·å houhf {- at -} IHEP {- dot -} AC {- dot -} CN Date: 2008-02-18 Dear all; I am a fresher of Refmac5. And now I'm trying to refine a protein and labelled RNA complex using Refmac. It's a Iodo-U labelled RNA. Unfortunately, these is no appropriate lib file in the current refmac dictionaries. So I use cif file which created by Refmc itself, surprisingly, the base of uridine distorted greatly. Could someone like to tell me how to make the appropriate cif file to solve this problem. Another question is that the RNA has a phosphate group in 5', How to define this in the cif file? Could someone help me? Thanks a lot!
