Gram-negative Bacterial Outer Membrane Construction Service

Gram-negative Bacterial Outer Membrane Construction Service

The cell envelope of Gram-negative bacteria contains a lipopolysaccharide (LPS)-rich outer membrane that serves as the bacterial cell's first line of defense in adverse physical and chemical environments. LPS macromolecules have negatively charged oligosaccharide domains that act as ion brushes, limiting the permeability of charged electrochemical reagents through the membrane. In addition to LPS, the outer membrane has radially extending O-antigen polysaccharide chains and β-barrel membrane proteins, which make bacterial membranes physiologically unique compared to phospholipid cell membranes. Elucidating the interactions of these macromolecular components and their roles in bacterial outer membrane integrity remains a challenge. CD BioSciences use computer-aided methods to provide gram-negative bacterial outer membrane construction service to help customers complete biofilm related research.

Specific Construction Approaches We Offer

  • To bridge the gap in our current understanding of Gram-negative bacterial membranes, we developed a coarse-grained outer membrane force field that is computationally affordable to simulate dynamic processes on physiologically relevant timescales.
  • The force field was benchmarked against available experimental and atomic simulation data to obtain properties such as film thickness, residue density distribution, area per lipid, gel-to-liquid crystal phase transition temperature, and ordering parameters.
  • We will compare the simulated structural and dynamic properties with the corresponding experimental data, and the force field we developed reproduces the overall physiology of LPS-rich membranes.
  • The affordability of the model we developed for long-term simulations helps determine the mechanistic aspects of the antibacterial effects of chemical agents and facilitates the design of antimicrobial peptides with enhanced outer membrane permeation properties.
