Microbial metabolism and enzyme function

The paper identifies PqqU as a high-affinity PQQ importer in Gram-negative bacteria, showing its structural basis and widespread distribution across diverse environments.

This study identifies a porin gene that facilitates ammonium uptake in methanotrophs, reduces ammonia toxicity and N2O production, and improves the sustainability of using ammonium as a nitrogen source in biomanufacturing.

This study demonstrates ectoine production from biogas by marine methanotroph-microalgae cultures, showing that osmotic stress enhances ectoine accumulation while high NaCl inhibits it.

This study examines how acetate affects CO2 fixation pathways in thermophilic bacteria, showing acetate suppresses the WL pathway and promotes the rTCA cycle in some species.

This study identifies and characterizes surface layer proteins in gammaproteobacterial methanotrophs, revealing their role in cell-envelope stability and environmental adaptation.

This study investigates how light and heavy lanthanides affect growth, lanthanide binding, and gene expression in Pseudomonas alloputida KT2440, revealing differential responses and a dimmer switch mechanism for lanthanide-dependent enzymes.

The paper uses molecular modeling to analyze the binding free energies of methanol and formaldehyde in methanol dehydrogenase, showing methanol binds more strongly and exits less readily than formaldehyde.

This study enriches methanotrophic microbiomes from paddy soils under different methane and copper conditions, finding Methylocystis dominance and ecological importance of methanobactin in Cu-deficient environments.

The paper identifies and characterizes two methanotrophic bacterial isolates from different methane-rich habitats, showing sequence homology and morphological differences.

The paper uses phylogenomic analysis of 189 Methylobacterium genomes to reveal four evolutionary groups and identify 45 candidate species, highlighting phyllosphere diversity and an ancient transition to plant association.

The paper sequenced and analyzed 13 Acetobacterium genomes to explore their phylogenetic diversity and metabolic capabilities, revealing conserved and variable metabolic traits across the genus.

The paper develops genome-scale metabolic models of methanotrophs from Lake Washington to study their interactions and metabolic responses under different environmental conditions.
