Bdellovibrio bacteriovorus is a microbial predator that offers promise as a living antibiotic for
its ability to kill Gram-negative bacteria, including human pathogens. Even after six decades …

The type IV secretion system (T4SS) is a versatile nanomachine that translocates diverse
effector molecules between microbes and into eukaryotic cells. Here, using electron …

The type VI secretion system (T6 SS ) is a versatile molecular weapon used by many
bacteria against eukaryotic hosts or prokaryotic competitors. It consists of a cytoplasmic …

The versatile enzyme system nitrogenase accomplishes the challenging reduction of N 2 and
other substrates through the use of two main metalloclusters. For molybdenum nitrogenase…

Type IV pili (T4P) are filamentous appendages found on many Bacteria and Archaea. They
are helical fibres of pilin proteins assembled by a multi-component macromolecular machine …

NifB is an essential radical S-adenosylmethionine (SAM) enzyme for nitrogenase cofactor
assembly. Previous studies show that NifB couples a putative pair of [Fe 4 S 4 ] modules (…

NifB is an essential radical SAM enzyme required for the assembly of an 8Fe core of the
nitrogenase cofactor. Herein, we report the X‐ray crystal structures of Methanobacterium …

NifB is a radical S-adenosyl-L-methionine (SAM) enzyme that is essential for nitrogenase
cofactor assembly. Previously, a nitrogen ligand was shown to be involved in coupling a pair of …

Nitrogenase iron (Fe) proteins reduce CO 2 to CO and/or hydrocarbons under ambient
conditions. Here, we report a 2.4-Å crystal structure of the Fe protein from Methanosarcina …

Nitrogenase utilizes an ATP‐dependent reductase to deliver electrons to its catalytic component
to enable two important reactions: the reduction of N 2 to NH 4 + , and the reduction of …
