Structural and biochemical analysis of a B12 superbinder

FEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
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 ...

Dynamic structural equation models synthesize ecosystem dynamics constrained by ecological mechanisms

Methods in Ecology and Evolution
Ecological analyses typically involve many interacting variables. Ecologists often specify lagged interactions in community dynamics (i.e. vector‐autoregressive models) or simultaneous interactions (e.g.

A Monte Carlo Study of the Residuals of System Estimators in the Presence of Multicollinearity

Ekoist Journal of Econometrics and Statistics
Residual analysis is often used to evaluate the precision of the parameter estimates of econometric models. Analysis of residuals from regression is an important way of assessing the performance of a regression model in achieving the goal of accounting ...

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

FEBS Letters, EarlyView.
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

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Simultaneous Equation of Concentration, Efficiency, and Competitiveness of Indonesia's CPO Industry: Impacts and Policies

Economia Agro-Alimentare
This study simultaneously analyzed the industrial concentration measured using CR4, technical efficiency measured using Stochastic Frontier Analysis (SFA), and competitiveness using the Revealed Comparative Advantage (RCA) approach of the CPO industry in
