Beyond the Enzyme‐Latch: A Narrative and Systematic Review of Enzymic Controls on Carbon Cycling in Peatlands

open access: yesGlobal Change Biology, Volume 32, Issue 5, May 2026.
Peatlands are vast carbon reservoirs, yet the processes that suppress plant‐matter decomposition and that can switch to carbon release under disturbance remain contested. One explanation is the Enzyme‐latch hypothesis, which proposes that enzymatic constraints ‘lock’ decomposition until peatlands are damaged.

Characterization of pectin lyases on pectins and methyl oligogalacturonates [PDF]

open access: yes, 1972
Pure saturated and unsaturated oligogalacturonic acids, including unsaturated monogalacturonic acid, were isolated and characterized. Their ultraviolet absorbance at 232 run, and their reactivities in the periodate thiobarbituric acid test and carbazole ...

Prédiction des Motifs de Phycobilines-lyases chez les cyanobactéries

open access: yes, 2010
Cyanobacteria are photosynthetic organisms which use sophisticated light-harvesting complexes called phycobilisomes to absorb light. The phycobilin-lyases are enzymes involved in phycobilisome biosynthesis.

Quinolone tolerance in Escherichia coli due to defects in the adenosine ribonucleotides de novo biosynthesis pathway

open access: yesmLife, Volume 5, Issue 2, Page 217-228, April 2026.
Abstract Central carbon metabolism is thought to link reactive oxygen species (ROS) with antibiotic‐mediated bacterial death. During enrichment screening of Escherichia coli with the first‐generation quinolone oxolinic acid, unstable antibiotic‐tolerant mutants containing deficiencies in purB were obtained.

Conformations of 2-Carboxy-1,4-butanedioic Acid as a Function of Ionization State in Dimethyl Sulfoxide

open access: yes, 2016
The conformational equilibria of 2-carboxy-1,4-butanedioic acid and its mono-, di-, and trianions were estimated by NMR couplings in dimethyl sulfoxide (DMSO).

A short peptide derived from late embryogenesis abundant proteins enhances acid tolerance in Escherichia coli via modulation of two‐component regulatory systems

open access: yesThe FEBS Journal, Volume 293, Issue 3, Page 781-805, February 2026.
Expression of the LEA‐K peptide in E. coli BL21 (DE3) improved bacterial viability under acidic stress (pH4), suggesting a protective function. RNA‐sequencing of LEA‐K‐expressing vs. non‐expressing cells revealed 283 differentially expressed genes (DEGs). In silico docking linked LEA‐K to two‐component systems (TCS) proteins (Rcs, BtsS/R, and EnvZ/OmpR)
