The mechanics of a continuous self-assembling surface-layer aids cell division in an archaeon

Sherman Foo, Ido Caspy, Alice Cezanne, Tanmay A. M. Bharat, Buzz Baum

The paper shows that the S-layer in Sulfolobus acidocaldarius aids cell division by reshaping the cytokinetic furrow through its flexible self-assembly, enhancing ESCRT-III-dependent division under mechanical stress.
