Structure‐Guided Engineering of a Ser192Ala Variant Enhances Bidirectional Catalysis in Amycolatopsis sulphurea L‐Alanine Dehydrogenase

ChemCatChem, Volume 18, Issue 15, 14 August 2026.
A rationally engineered Ser192Ala variant of Amycolatopsis sulphurea L‐alanine dehydrogenase (L‐AlaDH) exhibits ∼2‐fold higher catalytic efficiency in both reductive amination and oxidative deamination. Experimental characterization confirms maintained stability under tested conditions, highlighting its potential as an improved biocatalyst for ...

Validation of an ELISA assay for measurement of the metabolite of serotonin, 5‐hydroxyindole acetic acid (5‐HIAA), in canine urine

Journal of Small Animal Practice, Volume 67, Issue 8, Page 680-685, August 2026.
Objectives Serotonin (5‐hydroxytryptophan), implicated in a number of canine diseases, has a very short half‐life in the serum. Urine concentration of its breakdown product 5‐hydroxyindole acetic acid after an 8 hour fast is a more reliable measure of circulating serotonin in humans.
