[ccp4bb] distance range of salt bridges

2008-11-21 Thread Matt Colins
Dear all, I have a question about distance range of salt bridges. I understand that salt bridges within 4 angstroms are considered strong. However, at 5 angstroms or even 6 angstroms, are salt bridges nonexistent or just being weak? Thanks! Matt
