Zn parameters

[Steve Tetreault]

Hello everybody,

	I am currently refining the structure of a zinc-binding
protein and in order to properly set up my crystallographic
refinement of the complex with X-Plor, I need the covalent bond 
force field parameters between Zinc(II) and a histidine Nitrogen as 
well as those for Zinc(II) and a carboxylic Oxygen.  

	Can anyone out there supply me with the appropriate
parameters? Any help will be appreciated.

Steve.
