A functional chimaeric S-layer-enhanced green fluorescent protein to follow the uptake of S-layer-coated liposomes into eukaryotic cells.
The chimaeric gene encoding a C-terminally truncated form of the S-layer protein SbpA of Bacillus sphaericus CCM 2177 and the EGFP (enhanced green fluorescent protein) was ligated into plasmid pET28a and cloned and expressed in Escherichia coli. Just 1 h after induction of expression an intense EGFP fluorescence was detected in the cytoplasm of the host cells. Expression at 28 degrees C instead...
متن کاملExpression and cytosolic assembly of the S-layer fusion protein mSbsC-EGFP in eukaryotic cells
BACKGROUND Native as well as recombinant bacterial cell surface layer (S-layer) protein of Geobacillus (G.) stearothermophilus ATCC 12980 assembles to supramolecular structures with an oblique symmetry. Upon expression in E. coli, S-layer self assembly products are formed in the cytosol. We tested the expression and assembly of a fusion protein, consisting of the mature part (aa 31-1099) of the...
متن کاملS-Layer Protein Self-Assembly
Crystalline S(urface)-layers are the most commonly observed cell surface structures in prokaryotic organisms (bacteria and archaea). S-layers are highly porous protein meshworks with unit cell sizes in the range of 3 to 30 nm, and thicknesses of ~10 nm. One of the key features of S-layer proteins is their intrinsic capability to form self-assembled mono- or double layers in solution, and at i...
متن کاملOptimization of S-layer protein purification from Deinococcus radiodurans strain R1
S-layer proteins of Deinococcus radiodurans are the best self-assemble systems among other proteins that have an essential role in the fabrication of nanowires. Therefore, the purification of these proteins is necessary. The purpose of this research was to optimize the purification of s-layer protein from D. radiodurans with the response surface method. The three factors of SDS concentration, i...
متن کاملSurface-layer (S-layer) proteins sap and EA1 govern the binding of the S-layer-associated protein BslO at the cell septa of Bacillus anthracis.
The Gram-positive pathogen Bacillus anthracis contains 24 genes whose products harbor the structurally conserved surface-layer (S-layer) homology (SLH) domain. Proteins endowed with the SLH domain associate with the secondary cell wall polysaccharide (SCWP) following secretion. Two such proteins, Sap and EA1, have the unique ability to self-assemble into a paracrystalline layer on the surface o...
