Description
Ingrid E. Adriaans and others show how ATP-driven skin binding and chaining of germ actin MreB loosens skins locally. In 2026, the study looks at MreB from Geobacillus stearothermophilus using one-way glow, fat bubble binding, atomic force scope work, and solid-state NMR. MreB threads direct rod cell shape by guiding cell wall making around the rim.
Two-charge ions proved needed for fuel-bit binding, and unlike higher-cell actin, MreB bound ATP and ADP with similar grip. Single units made edge charge skin contacts, while Mg-ATP-made threads sank into the bilayer without breaking its layered phase and clearly loosened local skin. Loosening could steer cell wall building enzymes, and even ATP and ADP grip may tune the chaining-ready pool.
