charges on Asp, Glu, Arg, Lys residues

[Robert D Scavetta]

Hi all,

Sorry for the following ignorant question.  But I have never really have been
given a satisfactory answer to what may seem an easy question.

Why are the charges for Asp, Glu, Arg, and Lys set to zero for certain x-plor
runs?  Wouldn't one want the charges on, to mimic the actual charge state of
the protein in which data was collected?
