For complex RNA structures, * Molecular replacement can stumble * If made by simple T7 transcription methods (the most common way), the RNA would have EVERY U replaced with 5-bromo-U * Adding bromine to the 5 position of U could affect the structure (it would be replacing -H not -CH3

Hello, unless it's changed over the last couple of years, the pdb rightly used to let you deposit a structure with outliers, hopefully not too many, though ;-0 I take it the stalling you reported probably comes from whoever is looking over your shoulder. Best wishes, Jon Cooper. jon.b.coo...@pr

Hi I think It may be worthwhile submitting your model and data to PDB-REDO to see if (inter alia) you have applied any unconscious bias to your building that has resulted in these outliers, or over- or under-interpreted the data. It’s quick and easy to submit and requires remarkably little effo
