The (EAAAK)5 linker is shown to possess a pH-dependent auto-cleavage feature. In the range pH 6–7, the
 
target protein becomes automatically released from the fusion protein without proteolytic treatment.
 
Although the mechanism of this auto-cleavage property of an (EAAAK)5 linker is unclear, this feature has

Usage and Biology

In our design, we use it as a rigid linker linking two proteins to form one fusion protein. It can prevent the two proteins from interrupting each other while folding. A rigid linker that links two proteins to form one fusion protein. It repeats amino acids EAAAK three times to maintain distance of two proteins and preventing from interrupting each other while folding.
