[ccp4bb] Compound behaviour/vulnerability/truncation software/server

[Brenda Patterson]

Dear all,

I was wondering if anyone knew of any software or server that could predict
possible points of specific venerability to physical or chemical
stresses/attack, which may lead to likely truncation of a given 
compound? Another possibility would be software that would take a 
compound as an input
and then output truncated variants of this compound?
Cheers

Brenda
