Plasmid pOVC1_L4(EAAAK)3 from Dr. Harald Janovjak's lab contains the insert (EAAAK)3 linker and is published in J Mol Biol. 2019 May 29. pii: S0022-2836(19)30317-1. doi: 10.1016/j.jmb.2019.05.033.

Table 4 We determined the FRET efficiencies of ECFP-linker-EYFP proteins with linkers ranging in length from 25 to 73 amino acids and with glycine contents of 33.3% (GSSGSS), 16.7% (GSSSSSS), and 0% (SSSSSSS). The FRET efficiency decreased with an increasing linker length and was overall lower for linkers with less glycine. The fusion of the FimH, PapG, and CsgA proteins was generated by employing the five repeats of the EAAAK linker ([EAAAK] 5), which forms an alpha helix with a length of 39.95 Ȧ stabilized by five salt bridges between the Glu − and Lys + residues. Generation of Dimeric and Trimeric Genes Flexibility or rigidity of the linker between two fused proteins is an important parameter that affects the function of fusion proteins. In this study, we constructed a linker library with five elementary units based on the combination of the flexible (GGGGS) and the rigid (EAAAK) units. The original, short (G4S)1 flexible linker was compared against a long (G4S)4 flexible linker, a short (EAAAK)1 rigid linker, and a long (EAAAK)3 rigid linker (22, 23). CARs with modified linker sequences were expressed at full length and localized to the cell surface (Supplementary Fig. S2C and S2D).

Interestingly, the [EAAAK] 5 linker used in the fusion proteins does not contain B-cell epitopes and MHC class II-binding peptides. Moreover, the fusion proteins exhibited a high percentage of random coil structure, which have been reported in other models as principal components of antigens with flexible regions that allow protein-protein interactions ( Janin and Chothia, 1990 ; Chen et al Hello, I am preparing a fusion protein with mentioned sequences and I have doubts about the type of linker to use. I have seen in the literature that sometimes flexible linkers of this type of Here, the helical linker (EAAAK) was utilized to join the adjuvant and capsid toward the N‐terminal site of the vaccine construct to reduce the interaction with another protein region along with efficient separation. 36, 37 The AAY motif was used to join the CTL epitope as a linker to enhance the epitope separation. The original, short (G4S)1 flexible linker was compared against a long (G4S)4 flexible linker, a short (EAAAK)1 rigid linker, and a long (EAAAK)3 rigid linker . CARs with modified linker sequences were expressed at full length and localized to the cell surface (Supplementary Fig. S2C and S2D).

2016-11-11 · The typical rigid α-helical-forming linker (EAAAK)n (n ≤ 6) is utilized to link two domains of fusion enzymes by controlling a distance between them [36–38]. The long chain rigid linker peptide ER/K (5, 10 nm) had good effect for the expression of fusion protein [39, 40]. We obtained promising results in experiments with the linker containing the EAAAK motif, which forms a stable alpha-helical structure . Incorporation of such a linker between fusion partners resulted in improved expression and permitted for efficient surface display of the CotB-GGGEAAAKGGG-UreA protein. 2016-05-01 · (EAAAK) linker is an alpha-helix forming linker structure that is able to prevent the interference between two green fluorescent proteins .
