[ccp4bb] on resolution and explaination of the intersubunit bonds

[Smith Liu]

Dear All,
 
In order to acceptably explain the salt bridges, hydrophobic interactions and 
H-bonds among subunits in the crystal structure of a protein complex, is there 
a threshold resolution of the crystal, for example, if the crystal is poorer 
than 4A or 5A, the crystal structure solved cannot be used to acceptably 
explain the intersubunit interactions at the non-covalen bond level?
