Development of a tryptophan-based dual selection system reveals the spatial organization of S-layer assembly during cytokinesis in Sulfolobus acidocaldarius

The paper develops a tryptophan auxotrophy-based selection system in Sulfolobus acidocaldarius to study S-layer assembly during cytokinesis, revealing spatial localization of SlaA and SlaB at the division bridge.

Bridging the lipid divide: archaeal ESCRT-III binds phosphoinositol and polarises the cytokinetic membrane

This study shows that archaeal ESCRT-III homologue CdvB1 binds phosphoinositides and helps polarize the cytokinetic membrane in Sulfolobus acidocaldarius.

Adaptation of eukaryotic membrane homeostasis to species-specific cellular lipid landscapes

The paper investigates how membrane lipid homeostasis mechanisms adapt to species-specific lipid compositions in fission yeasts using lipidomics and transcriptomics.

Temporal and spatial coordination of DNA segregation and cell division in an archaeon.

This study investigates how DNA segregation and cell division are coordinated in archaea, identifying regulatory checkpoints and proteins involved in ensuring accurate genome distribution.

The mechanism of cell cycle dependent proteasome-mediated CdvB degradation in Sulfolobus acidocaldarius

This study identifies the mechanism of cell cycle-dependent proteasome-mediated CdvB degradation in Sulfolobus acidocaldarius, revealing a role for a novel transcription factor and proteasome-activating nucleotidase.

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

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.

A temperature sensitive mutant screen reveals translational stress-induced cell cycle regulation in a thermophilic archaeon

This study uses temperature-sensitive mutants in Sulfolobus acidocaldarius to identify a ribosomal mutation that blocks translation and prevents cell division, linking translation to cell cycle control.
