Nitrogenases are enzymes that convert atmospheric N2 into ammonia, thus providing bioavailable nitrogen to living organisms. Here, Maslać et al. describe a highly thermostable, simple nitrogenase from...

MemBrain v2 enables streamlined analysis of membranes in cryo-electron tomography by providing user-friendly tools for membrane segmentation, membrane protein localization and spatial analysis, suppor...

PilC/PilY1 proteins are tip-located adhesins of type IV pili (T4P) that are critical for T4P function in diverse behaviors including twitching moti...

Archaea can swim using rotating helical filaments called archaella. Here, Meshcheryakov et al. report that the cryo-EM structures of two types of archaella from Haloarcula marismortui display a unique...

Asgard archaeal mini microtubules suggest an archaeal origin of eukaryotic microtubules.

A specific isoform of PBP1b functions independently of the activator protein, LpoB, to drive generation of a wedge-like peptidoglycan structure that strengthens the division site in Escherichia coli.

Rumen ciliates are major contributors to enteric methane emissions from ruminant animals, yet the underlying mechanisms remain poorly understood. We present a catalog of 450 rumen ciliate genomes, wit...

Sulfolobus acidocaldarius is a thermoacidophilic archaeon with high potential for robust continuous bioprocesses under extreme conditions. In this stu…
