Dear CCLers,
           I am currently attempting to study a phosphorylated 
histidine residue:-

-C   O
  \  |
   N-P-O-H
  /  |
-C   O

Using the Weiner et.al. MM force field. 
I am unable to find parameters in any standard database
or in the literature.
If anyone has parameters for this or a sufficiently similar
system I would be eternally grateful for any assistance.
I am missing C-N-P and N-P-O angle parameters and C-N-P-O
torsional parameters.

Thank-you
