Hi, There are several semi-rational ways to design constructs on the basis of existing structures. It is important to remember that we only partially understand the protein expression and folding - which means that sometimes (way more often then I'd like) all the design considerations have to go out of the window and one has to painstakingly scan the termini in small increments.
If you're interested in further discussion, we should probably take this out of the list. Feel free to drop me a note. Artem > Hello > > I am designing a protein construct for structural biology.
