BACKGROUND Lipopolysaccharide (LPS), also referred to as endotoxin, is the major constituent of the outer leaflet of the outer membrane of virtually all Gram-negative bacteria. The lipid A moiety, which anchors the LPS molecule to the outer membrane, acts as a potent agonist for Toll-like receptor 4/myeloid differentiation factor 2-mediated pro-inflammatory(More)
BACKGROUND Extracellular expression of proteins has an absolute advantage in a large-scale industrial production. In our previous study, Thermobifida fusca cutinase, an enzyme mainly utilized in textile industry, was expressed via type II secretory system in Escherichia coli BL21(DE3), and it was found that parts of the expressed protein was accumulated in(More)
Secretion of cytoplasmic expressed proteins into culture medium has significant commercial advantages in large-scale production of proteins. Our previous study demonstrated that the membrane permeability of Escherichia coli could be significantly improved when Thermobifida fusca cutinase, without a signal peptide, was expressed in cytoplasm. This study(More)
Lipopolysaccharide (LPS) is located on the surface of Gram-negative bacteria and is responsible for maintaining outer membrane stability, which is a prerequisite for cell survival. Furthermore, it represents an important barrier against hostile environmental factors such as antimicrobial peptides and the complement cascade during Gram-negative infections.(More)
