Description
Flexible linker of 56 amino acids for translational fusion of protein domains. Used in the
BaKillus project to display pathogen-specific peptides on the surface of
B. subtilis with the YhcR/YhcS system to mediate adhesion of
B. subtlis to pathogens.
The YhcR/YhcS systems consists of four components: the sortase substrate with a signal peptide (
BBa_K1351008), a linker (this part) and a cell wall-anchoring domain (
BBa_K1351010) as well as the sortase YhcS itself (
BBa_K1351011), whose overexpression increases the efficiency of the surface display.
This part was generated in a modified version of RFC25, where a strong Shine Dalgarno Sequence (SD) is included, and has the following prefix and suffix:
{|
|prefix with EcoRI, NotI, XbaI, SD and NgoMIV:
|
GAATTCGCGGCCGCT
TCTAGAGT
AAGGAGGA
GCCGGC
|-
|suffix with AgeI, SpeI, NotI and PstI:
|
ACCGGTTAAT
ACTAGTAGCGGCCGCCTGCAG
|}
Sites of restriction enzymes generating compatible overhangs have the same color:
EcoRI and
PstI in blue,
NotI in green,
XbaI and
SpeI in red,
NgoMIV and
AgeI in orange. Shine-Dalgarno sequence and stop codons are underlined.
Notes
The linker sequence corresponds to the linker used in Liew et. al., 2012.
Oligonucleotides were designed as precut by EcoRI and PstI to shorten the synthesized fragments and to simplify the cloning into pSB1C3
Source
This part was generated by annealing synthesized oligonucleotides followed by ligation in pBS1C3:
