Plants (Basel)
. 2023 Jul;
12(14).
PMID: 37514285
Plant growth-promoting rhizobacteria (PGPR) are members of the plant rhizomicrobiome that enhance plant growth and stress resistance by increasing nutrient availability to the plant, producing phytohormones or other secondary metabolites,...

PMID: 37260681
bv. viciae () UPM791 effectively nodulates pea and lentil, but bacteroids contain a number of proteins differentially expressed depending on the host. One of these host-dependent proteins (C189) is similar...

Microbiology (Reading)
. 2023 Feb;
169(1).
PMID: 36748569
We previously showed that specific polyamines (PAs) present in the extracellular environment markedly affect extracellular polysaccharide (EPS) production, biofilm formation and motility in Rm8530. We hypothesized that extracellular PA signals...

Front Mol Biosci
. 2022 Sep;
9:923042.
PMID: 36172042
The regulation of the synthesis of L-tryptophan (L-Trp) in enteric bacteria begins at the level of gene expression where the cellular concentration of L-Trp tightly controls expression of the five...

Vargas-Lagunas C, Mora Y, Aguilar A, Reyes-Gonzalez A, Arteaga-Ide A, Dunn M, et al.
Microbiology (Reading)
. 2022 Jan;
168(1).
PMID: 35077343
Biotin is a key cofactor of metabolic carboxylases, although many rhizobial strains are biotin auxotrophs. When some of these strains were serially subcultured in minimal medium, they showed diminished growth...

Proc Natl Acad Sci U S A
. 2022 Jan;
119(2).
PMID: 34996869
NMR-assisted crystallography-the integrated application of solid-state NMR, X-ray crystallography, and first-principles computational chemistry-holds significant promise for mechanistic enzymology: by providing atomic-resolution characterization of stable intermediates in enzyme active sites, including...

Protein Sci
. 2021 Nov;
31(2):432-442.
PMID: 34767267
Antibiotic resistance is a continually growing challenge in the treatment of various bacterial infections worldwide. New drugs and new drug targets are necessary to curb the threat of infectious diseases...

Biochemistry
. 2021 Oct;
60(42):3173-3186.
PMID: 34595921
The tryptophan synthase (TS) bienzyme complexes found in bacteria, yeasts, and molds are pyridoxal 5'-phosphate (PLP)-requiring enzymes that synthesize l-Trp. In the TS catalytic cycle, switching between the open and...

PMID: 34160574
The metalloenzyme arginase hydrolyzes l-arginine to produce l-ornithine and urea. In bacteria, arginase has important functions in basic nitrogen metabolism and redistribution, production of the key metabolic precursor l-ornithine, stress...
