The divergent early divisome: is there a functional core?

G Santiago-Collazo, PJB Brown, AM Randich - Trends in Microbiology, 2024 - cell.com
The bacterial divisome is a complex nanomachine that drives cell division and separation.
The essentiality of these processes leads to the assumption that proteins with core roles will …

Anchors: A way for FtsZ filaments to stay membrane bound

A Naha, DP Haeusser, W Margolin - Molecular Microbiology, 2023 - Wiley Online Library
Most bacteria use the tubulin homolog FtsZ to organize their cell division. FtsZ polymers
initially assemble into mobile complexes that circle around a ring‐like structure at the cell …
