David- it sounds like you need to do some molecular dynamics.  There are 
some (relatively) user friendly packages (e.g. insight with the discover 
module, xplor etc.) that will allow you to "thread" your AA sequence into 
a structure coordinate file.  After minimizing your structure, you can 
compare the results with the original "anchor" structure and make some 
predictions.  

Best regards, 
Hans
