Hi Mitra,

The answer, like most answers about protein crystallization, is "It 
depends."

The thing is, most proteins with N-terminal signal sequence are not 
(completely) folded when the signal is intact. But since you mentioned that 
yours is active with the signal, it MAY crystallize. However, I would 
suggest that you perform crystallization screening using both the intact and 
signal sequence-removed constructs. This way you can save a lot of time if 
one of them does not crystallize well.

Hi everybody
 
I wanna crystallize a 16 kDa protein with signal peptide on the N-terminl, is
it correct? Protein activity is good with signal peptide but I don't
know if this signal peptide effect on 3D structure? Would you please guide me?
 
Best 
 
Mitra
