Energy flux controls tetraether lipid cyclization in Sulfolobus acidocaldarius
bioRxiv, 2019 Microorganisms regulate the composition of their membranes in response to environmental cues. Many archaea maintain the fluidity and permeability of their membranes by adjusting the number of cyclic moieties within the cores of their glycerol ...

Snapshots of Motion: A Novel Structural Intermediate Reveals Conserved Dynamics in Archaeal DNA Ligases. [PDF]
ProteinsABSTRACT We present the first x‐ray crystallographic structural evidence of an archaeal DNA ligase showing the AMP covalent adduct together with further cofactor hydrolysis, capturing a transient intermediary in the first step of the ligation reaction, triggered by the pyrophosphate hydrolysis.

Electron cryo-microscopy reveals the structure of the archaeal thread filament
Nature Communications, 2022 Pili are filamentous appendages on the surface of bacteria and archaea, and play roles in multiple processes such as adhesion, motility and horizontal gene transfer. Here, Gaines et al. describe the structure of a new type of pilus, termed ‘thread’, from

Asymmetric Reduction of Unactivated Alkenes. [PDF]
ChemistryUnactivated alkenes rank among the most inert functional groups in synthesis and their selective reduction remains challenging. This Review charts the evolution from classical metal‐catalyzed hydrogenation to radical hydrogen atom transfer (HAT) and emerging biocatalytic concepts, highlighting how complementary mechanistic strategies, including the ...

Surface resistance to SSVs and SIRVs in pilin deletions of Sulfolobus islandicus
Molecular Microbiology, 2019 Characterizing the molecular interactions of viruses in natural microbial populations offers insights into virus–host dynamics in complex ecosystems. We identify the resistance of Sulfolobus islandicus to Sulfolobus spindle‐shaped virus (SSV9) conferred ...
