Study of the Photoinduced Fate of Selected Contaminants in Surface Waters by HPLC‐HRMS

Rapid Communications in Mass Spectrometry, Volume 39, Issue 17, 15 September 2025.
ABSTRACT Rationale Photoinduced transformation of contaminants of emerging concern (CECs) can occur in aquatic environment and could lead to the formation of transformation products (TPs) of greater concern than the parent compounds. For such, the fate of epoxiconazole, hymecromone, and coumarin in water was investigated by simulating photoinduced ...

The Pseudoenzyme β‐Amylase9 From Arabidopsis Activates α‐Amylase3: A Possible Mechanism to Promote Stress‐Induced Starch Degradation

Proteins: Structure, Function, and Bioinformatics, Volume 93, Issue 6, Page 1189-1201, June 2025.
ABSTRACT Starch accumulation in plants provides carbon for nighttime use, for regrowth after periods of dormancy, and for times of stress. Both ɑ‐ and β‐amylases (AMYs and BAMs, respectively) catalyze starch hydrolysis, but their functional roles are unclear.
