The mycomembrane proteins PorH and ProtX are inserted at polar growth zones and linked to the cell wall.

PorH and ProtX are assembled at cell poles in Corynebacterium glutamicum, linking the mycomembrane to peptidoglycan synthesis with a high-confidence hetero-oligomeric structure.

• Why it matters: Understanding how mycomembrane proteins are assembled and connected to the cell wall is crucial for insights into bacterial envelope integrity and pathogenicity, especially in organisms like Mycobacterium tuberculosis.
• What they did: Researchers used AlphaFold2 modeling, fluorescence assays, and genetic analysis to study PorH and ProtX, revealing their assembly at PG synthesis zones and their dependence on PorA.
• The result: The findings demonstrate that mycomembrane proteins are coordinated with cell wall biogenesis and physically linked, enabling potential targets for disrupting envelope integrity in pathogenic bacteria.
