Multi-pass Transmembrane Proteins and β-barrels

Multi-pass Transmembrane Proteins and β-barrels

In multi-pass transmembrane proteins, the polypeptide chain crosses the membrane more than once. The transmembrane polypeptide chain either forms an α-helix or β-strand structure. α-Helix containing multi-pass transmembrane proteins are ubiquitous, whereas β-strand containing ones are mainly found in gram-negative bacteria, mitochondria, and chloroplasts.

Background:

Coarse-grained (CG) models are essential for simulating membrane proteins at biologically relevant scales.
Existing CG lipid models face limitations in stability and efficiency beyond critical sizes, hindering large-scale simulations.
These limitations stem from slow relaxation dynamics and scale-dependent instabilities.

Conclusions:

The optimized CG lipid model enables accurate and efficient large-scale simulations of membrane proteins.
This work provides a methodological framework for addressing scale-dependent issues in CG simulations.
The findings facilitate a deeper understanding of mechanosensitive channel function and membrane dynamics.
