Type 1 diabetes mellitus (T1DM) is an auto-immune disease while oral administrating its autoantigens could be a treatment of T1DM. To express human insulin gene (ins) in lactic acid bacteria (LAB) for oral vaccine, ins gene was replaced by LAB bias codon and an 8-amino-acid-residue linker peptide forming a beta-turn was designed to link insulin chain A and(More)
According to the knowledge gained from engineering of nisinZ, using plasmid pHJ201 DNA as template, NisinZ was mutated by site-directed mutagenesis, NisinZ mutant T8S contains Serine at position 8 instead of Threonine, NisinZ mutant N27K/H31K contains Lysine at position 27 and 31, respectively, instead of Asparagine and Histidine and NisinZ mutant T2S/ H31K(More)
Nattokinase (NK) is a health product for the prevention and potential control of thrombosis diseases. To explore the possibility of enhancing NK production in Bacillus subtilis by altering the promoter of NK gene (PaprN), we tested several methods. We substituted the wild-type -10 box (TACAAT) of PaprN with the consensus sequence (TATAAT) of r-dependent(More)
Lactic acid bacteria (LAB) are important industrial microorganism used in the production and preservation of food-stuffs. Recently, considerable advances have been made in the genetics and molecular biology of LAB. These have resulted in the construction of food-grade gene expression systems for these bacteria. This paper aims to review the essential(More)
