Dear VMD Users,

 I have two different protein structures, belonging to two different
enzymes. The only common thing they have is the coordination of the central
zinc ion,; made by two histidines and one glutamate. I am trying to align
these two structures according to this two histidines and the central zinc

 I'm not sure how to overlap these two structures according to these three
residues which have different resid in each structure.

 Can you help me with this?

 Thank you for your help in advance,
