We often have good luck using protease cleavage sites as linkers. They're evolved to have certain flexibility to them and they usually have a healthy mixture of hydrophobic and hydrophilic amino acids. As a delightful bonus they also offer the option to separate the two partners at will. Artem >

I recently had some success in this area. My approach was to get lucky when I guessed the linker. In this case, my linker became ordered which seemed to help my fusion construct settle down enough to exhibit density. My linker sequence came was (approximately) alternating hydrophilic and hy

Hi People, Could anyone point me to successful examples for two unrelated proteins that have been stitched together into one single polypeptide chain with flexible amino acids to create a functional chimera that was subsequently crystallized. I've looked up a few. I am particularly intere
