Single-molecule probing of the conformational homogeneity of the ABC transporter BtuCD, Published online: 18 June 2018; doi:10.1038/s41589-018-0088-2

A single-molecule approach combined with molecular dynamics simulations to examine the conformational dynamics of the Escherichia coli ABC transporter BtuCD defines a coordinated sequence of events leading to unidirectional transport.

Scavenging of superoxide by a membrane-bound superoxide oxidase

Scavenging of superoxide by a membrane-bound superoxide oxidase, Published online: 18 June 2018; doi:10.1038/s41589-018-0072-x

The membrane-bound enzyme CybB can directly oxidize superoxide to molecular oxygen and transfer the sequestered electrons to ubiquinone in vitro, providing a mechanism for superoxide scavenging distinct from that of superoxide dismutase.

The antibacterial microvionin contains two new lanthipeptide modifications, a triamino-dicarboxylic acid (avionin) and an N-terminal guanidino fatty acid, that lead to the establishment of the lipolanthine natural product class.

The Jumonji-C oxygenase JMJD7 catalyzes (3S)-lysyl hydroxylation of TRAFAC GTPases

The Jumonji-C oxygenase JMJD7 catalyzes (3<i>S</i>)-lysyl hydroxylation of TRAFAC GTPases, Published online: 18 June 2018; doi:10.1038/s41589-018-0071-y

Structural, biochemical and cellular studies reveal JMJD7 to be a Jumonji-C oxygenase that catalyzes (3S)-lysyl hydroxylation of the translation factor family of GTPases, DRG1 and DRG2.

Vitamin B12 import is all about timing

Vitamin B<sub>12</sub> import is all about timing, Published online: 18 June 2018; doi:10.1038/s41589-018-0087-3

Single-molecule techniques combined with molecular dynamics simulations allowed visualization of a surprisingly high level of conformational homogeneity in the transport cycle of an ABC import system, BtuCD-F, and revealed an unexpected tight coupling of distinct conformational states responsible for vitamin B12 binding, transport and release.
