Open AccessThe cryo-EM structure of the bacterial flagellum cap complex suggests a molecular mechanism for filament elongation
The bacterial flagellum is a remarkable molecular motor, whose primary function in bacteria is to facilitate motility through the rotation of a filament protruding from the bacterial cell. A cap complex, consi...

Open AccessExtra Territorial Excursions by European badgers are not limited by age, sex or season
European badgers (Meles meles) in medium and high density populations show strong territorial behaviour. Territories in these populations are contiguous, well-marked and often unchanging over many years. Howev...

Open AccessBacterial periplasmic nitrate and trimethylamine-N-oxide respiration coupled to menaquinol-cytochrome c reductase (Qcr): Implications for electrogenic reduction of alternative electron acceptors
The periplasmic reduction of the electron acceptors nitrate (Em +420 mV) and trimethylamine-N-oxide (TMAO; Em +130 mV) by Nap and Tor reductases is widespread in Gram-negative bacteria and is usually considered t...

Indicators of Ecological Integrity
Freshwater Ecological Integrity (EI) incorporates the concepts of ecosystem “health”, unimpaired structure, composition and function and a capacity for self-renewal and, as such, it is a holistic advance over ...

Metabolomic Analysis of Campylobacter jejuni by Direct-Injection Electrospray Ionization Mass Spectrometry
Direct-injection mass spectrometry (DIMS) is a means of rapidly obtaining metabolomic phenotype data in both prokaryotes and eukaryotes. Given our generally poor understanding of Campylobacter metabolism, the hig...
