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 ...

In this paper we establish necessary and sufficient optimality conditions for a nondifferenriable, nonconvex semi-infinite vector optimization problem involving locally Lipschitz functions, whose constraints are required to depend continuously on an ...

Optimisation of a Third Order System
A general algebraic method of optimising a third order system is presented. The method consists of extending Pontryagin's Maximum Principle to the infinite interval case and reducing the characteristic two point boundary value problem to that of the ...

Chain Conditions for Subgroups of Infinite Order or Index
Various weakened forms of the maximal condition on subgroups max and the minimal condition on subgroups min have been proposed, the best known being the weak maximal and minimal conditions of \textit{D. I. Zajtsev} [Dokl. Akad. Nauk. SSSR 178, 780-782 (1968; Zbl 0167.28803)].

How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

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

Unions of chains of subgroups of a topologucal group
We consider the following problem: If a topological group G is the union of an increasing chain of subgroups and certain cardinal invariants of the subgroups in the chain are known, what can be said about G?
