When you say a break, does it mean like none continuous backbone? or a
"kink" due to an unnatural amino acid?.
I am not familiar with your term "kink". In the case of a break due to two
chains, capping should do the job it supposed to and dynamics will be what
it supposed to (assuming you run long enough). If this is an unnatural
amino acid, and you are taking parameters from CGenFF server, based on
the penalty value you get, you should be able to determine the quality of
your parameters (assuming you are using CHARMM). If the penalties are low
(high does not mean they are bad either), they will be able to mimic the
"kink" in your protein. Without exactly knowing what is the "kink"
structure is you are talking about, I can only tell you this much.
