Hello everyone
>From electron density, It looks like one of the arginines in my protein is
post-translationally modified as phospho-arginine. How to make sure it's a
real phospho-arginine, not an arginine interacting with phosphate or
acetate ion? The resolution of the structure is 2.3 A. Can
Dear Jacob,

contribution of f' and f" is still affected by the fall off from the ADPs, i.e.
they also fall off exponentially, even for high quality crystals with a very
low B-factors.
The effect that you describe, however,
