Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

Spin-dependent transport of interacting electrons in mesoscopic systems [PDF]
Spin-dependent electronic transport properties of mesoscopic systems are studied using the nonequilibrium Green function formalism. In the first part we examine the influence of short-range electron-electron interactions on the conductance of quantum ...

Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Phosphorylation disrupts long-distance electron transport in cytochrome c
Electron transfer between mitochondrial cytochrome c and subunit of cytochrome bc 1 can proceed at long distance. Here the authors investigate further the mechanism and show phosphorylation regulation of the interactions between the protein partners in ...

Electron transport through double quantum dots in an Aharonov-Bohm ring [PDF]
Quantum dots (QDs), which are formed by a double barrier resulting in resonant-state electrons, are one of the ideal experimental tools to confine electrons and to study the tunneling of an electron through a double barrier in a one-dimensional ...

Artificial molecular machines and motors—Design and control of nanoscale motion
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Ascorbate biosynthesis in mitochondria is linked to the electron transport chain between complexes III and IV [PDF]
Ascorbic acid is synthesized from galactono-γ-lactone (GL) in plant tissues. An improved extraction procedure involving ammonium sulfate precipitation of membrane proteins from crude leaf homogenates yielded a simple, quick method for determining tissue ...
