In addn., the MIC value of the hybrid protein was 23.1 μM, which indicates poor activity against E. coli. When we used three Glu-Ala-Ala-Ala-Lys (EAAAK) peptide sequences as a helical linker to fuse the two proteins, the resultant hybrid protein had much higher antimicrobial activity than the parental antimicrobial 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. We introduced helix-forming peptide linkers A(EAAAK)nA (n = 2-5) between two green fluorescent protein variants, EBFP and EGFP, and investigated their spectral properties. The fluorescence resonance energy transfer from EBFP to EGFP decreased as the length of the linkers increased. peptide linkers A (EAAAK) A (n⍧2–5) between two green ﬂuorescent protein variants, EBFP and EGFP, and investigated their spectral properties. 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 third linker is an α-helix-forming linker (A(EAAAK) 4 ALEA(EAAAK) 4 A, designated as “(H4) 2 ” in Table 4) with the longest length of 50 amino acids and a rigid, extended structure [20, 40].

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 .

Next, the longer 30 aa flexible peptide was combined with the helical (H4) 2 peptide, which is 52 aa but can have a similar length to the extended 30 aa flexible peptide with its helical structure. 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 construct was expressed in E. coli BL21 (DE3) cells according to the manufacturer’s recommendations. For purification, cells were disrupted in lysis buffer (20 mM Tris-HCl (pH 8.0) and 300 mM NaCl) by sonication. From left to right, from top to bottom, the linkers are (GGGGS)3, (EAAAK)3, S(EAAAR)4 and A(EAAAK)4ALEA(EAAAK)4A respectively. From the result above, we came to a conclusion that connecting the proteins in the order of Cns2, linker, and Cns1 was better than the reverse order.

Cas9 molecules can be used to create a break in a genomic region of interest. To increase the likelihood that the break is repaired by HDR (homology-directed repair), the cell can be contacted with molecules that bring a template nucleic acid in close proximity to the break, under conditions that allow the cell to repair the break RFP with EAAAK linker and His Tag (BBa_K2382013) This is a fragment of BBa_K2382010.

These changes can be as small as the rotation of one or a few side-chain dihedral angles or involve concerted motions in larger portions of the three-dimensional structure; both kinds of motions can be important for biological function and allostery.

The peptide linker (GGGGS) 2 resulted in the best fusion, whose catalytic efficiency had a net increase of 326% for the Glu and of 43% for the Xyl. The two moieties of a fusion with the linker (EAAAK) 3 also showed net increases of 262 and 31% in catalytic efficiency. EAAAK, AAY and GPGPG linkers were used to construct the multi-epitope subunit vaccine (MEV), linking both suitable CTL and HTL epitopes. TLR 4-agonist (APPHALS) was used as Adjuvant [12].
