A Bacillus subtilis gene encoding a protein similar to nucleotide sugar transferases influences cell shape and viability.

Cloning of the Gene Encoding M2e of Influenza Virus in B. subtilis

Background and Aims: The ectodomain of matrix protein of influenza virus is a weak immunogen that is highly conserved among all subtypes of influenza A virus. Tandem repeats of these genes along with linker were used to enhance immunogenicity of M2e protein and so it can be served as a universal vaccine in both humans and livestock. Materials and Methods: In this study, the sequences of extra-d...

Expression and Secretion of Cyan Fluorescent Protein (CFP) in B. subtilis using the Chitinase Promoter from Bacillus pumilus SG2

Background: Improved cyan fluorescent protein (ICFP) is a monochromic, green fluorescent protein (GFP) derivative produced by Aequorea macrodactyla in a process similar to GFP. This protein has strong absorption spectra at wavelengths 426-446 nm. ICFP can be used in cell, organelle or intracellular protein labeling, investigating the protein-protein interactions as well as assessing the promote...

MOLECULAR CLONING AND EVALUATION OF WILD PROMOTER IN EXPRESSION OF BACILLUS SPHAERICUS PHENYLALANINE DEHYDROGENASE GENE IN BACILLUS SUBTILIS CELLS

To evaluate the role of wild promoter of L-phenylalanine dehydrogenase (PheDH) gene, referred to as pdh, from Bacillus sphaericus in expression, cloning of pdh gene in Bacillus subtilis was performed. The whole pdh gene was cloned in pHY300PLK shuttle vector and amplified, construct (pHYDH) then transformed in B. subtilis ISW1214 and E. coli JM109. The pdh endogenous promoter presented no effec...

Bacillus subtilis as a Host for Recombinant Hemagglutinin Production of the Influenza A (H5N1) Virus

Abstract Background and Aims: Influenza A(H5N1) viruses  circulating in animals might evolve and acquire the ability to spread from  human to human and thus start a pandemic. Hemagglutinin (HA) has been shown to play a major role in binding of influenza virus to its target cell and the main neutralizing antibody responses elicit against this region. Recent studies have shown that...
