Thermotolerant D‐Hydantoinases for Efficient and Stereoselective Intermediate Synthesis of (R)‐3‐Isobutylglutaric Acid Monoamide, a Key Intermediate in Pregabalin Production

open access: yesMicrobial Biotechnology, Volume 19, Issue 3, March 2026.
We engineered thermo‐alkali‐stable D‐hydantoinases via mutagenesis (M63A/F65H/C317T) to resolve Pregabalin's challenging chiral splitting, achieving ee value > 97% for key intermediate (R)‐3‐isobutylglutaric acid monoamide (R‐IBM) synthesis under extreme conditions (pH 10, 70°C–80°C).

Identification of a novel link connecting indole‐3‐acetamide with abscisic acid biosynthesis and signaling

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2452-2466, March 2026.
Summary Plants orchestrate their developmental processes and responses to environmental stimuli through a sophisticated network of small signaling molecules, termed phytohormones. Among these, auxins are recognized for their role in promoting plant growth.

Coupling Nitrogenous Organic Wastewater Treatment and Biorefinery via N‐Cycling Bacterium

open access: yesAdvanced Science, Volume 13, Issue 7, 3 February 2026.
The vast reservoir of nitrogenous organic pollutants in industrial wastewaters can serve as untapped carbon‐nitrogen resources. This study employs the newly discovered Paracoccus sp. ZQW‐1 as a versatile chassis to simultaneously achieve N‐methylpyrrolidone (NMP) wastewater depuration and polyhydroxybutyrate (PHB) synthesis.

Auxin Amidohydrolases – From Structure to Function: Revisited [PDF]

open access: yesCroatica Chemica Acta, 2018
The control of plant growth and development is a well-coordinated process between exogenous and endogenous signals. Auxins are plant hormones belonging to the endogenous signals, which control a vast array of different processes. While auxins are growth promoting at low concentrations, higher levels are often inhibitory. Therefore, the tight control of

Purification and properties of formylglutamate amidohydrolase from Pseudomonas putida [PDF]

open access: yesJournal of Bacteriology, 1987
Formylglutamate amidohydrolase (FGase) catalyzes the terminal reaction in the five-step pathway for histidine utilization in Pseudomonas putida. By this action, N-formyl-L-glutamate (FG) is hydrolyzed to produce L-glutamate plus formate. Urocanate, the first product in the pathway, induced all five enzymes, but FG was able to induce FGase alone ...

Exploring the Potential and Evaluating Hydrocarbon Degradation by Novel Antarctic Dietzia and Pusillimonas Isolates From a Pristine Environment

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 1, February 2026.
The Antarctic Dietzia and Pusillimonas isolates were tested for bioremediation applications. Genomic analyses revealed the potential to degrade complex organic compounds, potential virulence factors and resistance genes. Physiological assays showed a wide range of adaptation to abiotic factors and sensitivity to different groups of antibiotics ...

Determination of cephalosporin-C amidohydrolase activity with fluorescamine

open access: yesJournal of Pharmacy and Pharmacology, 1989
Abstract A spectrophotometric procedure for the assay of cephalosporin-C amidohydrolase activity, based on the determination of the 7-aminocephalosporanic acid (7-ACA) produced in the hydrolysis of cephalosporin-C by the enzyme, is described. This procedure can be used to detect 7-ACA over a range of 10 to 200 μg mL−1.

Untersuchungen zum Ursprung der Substratspezifität von Enzymen der Amidohydrolase‐Superfamilie

open access: yesAngewandte Chemie, Volume 138, Issue 4, 22 January 2026.
Umfassende Analysen zweier Enzymklassen aus der Amidohydrolase‐Superfamilie (AHS) ergaben, dass die Katalyse über eine 1,4‐ bzw. 1,6‐nukleophile konjugierte Addition abläuft und diese Eigenschaft die Substratspezifität bestimmt. Obwohl alle Substrate und Produkte vollständig achiral sind, führt dieser mechanistische Unterschied zu einer invertierten ...

Decoding Urease Inhibition: A Comprehensive Review of Inhibitor Scaffolds

open access: yesChemMedChem, Volume 21, Issue 2, January 2026.
Representative functional groups known for urease inhibition are reviewed within diverse scaffolds using structure–activity analyses to identify features associated with high inhibitory activity. Urease is a metalloenzyme produced by a wide range of organisms and plays a critical role in nitrogen microbial metabolism by catalyzing the hydrolysis of ...
