The Presence of Pyrrolo Quinoline Quinone (PQQ) in Eukaryotic Tissue Extracts

, 2021
The pyrroloquinoline quinone (PQQ) is a novel cofactor of certain bacterial enzymes. It was described for the first time in Methylobacterium extorquens associated to ethanol dehydrogenase (FloresEncarnación et al., 2004; Misra et al., 2012; Shen et al ...

Functional Role of Lanthanides in Enzymatic Activity and Transcriptional Regulation of Pyrroloquinoline Quinone-Dependent Alcohol Dehydrogenases in Pseudomonas putida KT2440

mBio, 2017
The oxidation of alcohols and aldehydes is crucial for detoxification and efficient catabolism of various volatile organic compounds (VOCs). Thus, many Gram-negative bacteria have evolved periplasmic oxidation systems based on pyrroloquinoline quinone ...

A ‘Genome‐First’ Framework for Next‐Generation Bioinputs: From Functional Mining to Rational Synthetic Microbial Communities

Environmental Microbiology, Volume 28, Issue 5, May 2026.
I propose a ‘genome‐first’ framework to collapse the phenotypic bottleneck in bioinput discovery. By integrating multi‐layered genome mining and reverse ecology, this paradigm enables the rational design of stable synthetic microbial communities for a data‐driven and sustainable agricultural bioeconomy.

Electroenzymatic Cascades for Nitrogen Upgrading: Beyond Ammonia Towards Value‐Added Nitrogen Chemicals

ChemCatChem, Volume 18, Issue 7, 14 April 2026.
This review maps how electroenzymatic cascades that couple nitrogen‐cycle enzymes with C─N bond forming auxilary enzymes, powered by direct electron transfer (DET) or mediated electron transfer (MET), can upgrade N2 and waste nitrogen streams into value‐added amines, amides, amino acids, and other nitrogen‐based chemicals.

Crystal structure of a calcium(II)–pyrroloquinoline quinone (PQQ) complex outside a protein environment

Acta Crystallographica Section C Structural Chemistry, 2020
Pyrroloquinoline quinone (PQQ) is an important cofactor of calcium- and lanthanide-dependent alcohol dehydrogenases. The crystal structure of a Ca–PQQ complex (Ca3PQQ2·13H2O) is reported for the first time outside a protein environment.

Molecular Mechanisms of Plant Growth–Promoting Rhizobacteria (PGPR) in Biofertilization and Disease Suppression of Crops

International Journal of Agronomy, Volume 2026, Issue 1, 2026.
Plant growth–promoting rhizobacteria (PGPR) are beneficial soil bacteria that colonize the rhizosphere and enhance plant growth through direct and indirect mechanisms, including nutrient solubilization, phytohormone production, suppression of phytopathogens, and activation of plant defense mechanisms.
