Implication

All-atom simulations reveal the impact of lipoglycan concentration on mycobacterial membrane structure and dynamics, suggesting implications for virulence.

Key Points

This study aims to investigate how varying concentrations of lipomannan and lipoarabinomannan affect the structure and dynamics of mycobacterial inner membranes.
Conducted all-atom molecular dynamics simulations of mycobacterial inner membranes incorporating lipomannan and lipoarabinomannan.
Constructed symmetric and asymmetric membrane systems to analyze lipid dynamics and properties.
Assessed shifts in polysaccharide chain orientations relative to lipid composition and membrane structure.
The inner leaflet remained stable and fluid with phospholipid/PIM-rich composition.
High concentrations of LM/LAM caused polysaccharide chains to transition to a compact brush-like state, reducing solvent-accessible volume.
Increased lipoglycan presence slowed lipid diffusion, indicating dynamic interactions between lipid leaflets.
