Flexible Glycine Glycine Serine (GGS) Linker (54 aa)

Usage and Biology

Designing fusion proteins is sometimes tricky because of potential misfolding and protein steric hindrance. To avoid these problems, linkers are often used. They can be either rigid or flexible. Flexible linkers are used to enable a certain degree of movements to the different parts of the newly generated fusion protein. Moreover, they allow to generate fusion proteins without interfering with the function of each domain. They are constituted with a succession of Gly and Ser residues. This linker has the following formula: (Gly-Gly-Ser)_n , where n = 54. These sequences can be repeated in order to obtain an appropriate length separation of functional domains and can also be shortened to maintain inter-domain reactions.
