The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

The formation and evolution of planetary systems are linked to their host stellar environment. In this study, we employ a pebble-accretion-based planet population synthesis model to explore the correlation between planetary properties and stellar mass ...

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

Korg: Fitting, Model Atmosphere Interpolation, and Brackett Lines
We describe several updates to Korg , a package for 1D LTE spectral synthesis of FGKM stars. Built-in functions to fit observed spectra via synthesis or equivalent widths make it easy to take advantage of Korg 's automatic differentiation.

Stellar Population Properties of UCDs and Early-Type Dwarf Nuclei
We analyze the stellar population parameters of seven ultra-compact dwarfs (UCDs) in the Virgo cluster. We find that the stellar population properties of UCDs are similar to those nuclei of early-type dwarf galaxies (dEs) that lie in the dense region of ...

Prospecting the protein design landscape
This review outlines the current state of various protein design approaches. We discuss the current possibilities enabled by recently released tools, highlight future avenues to pursue in protein design, and underscore the crucial role of key databases and resources for successful protein design workflows.

Gaia Net: Toward Robust Spectroscopic Parameters of Stars of all Evolutionary Stages
We present a new processing of XP spectra for 220 million stars released in Gaia DR3. The new data model is capable of handling objects with T _eff between 2000 and 50,000 K and with $\mathrm{log}\,g$ between 0 and 10, including objects of multitude of ...
