Cooperative Photometallobiocatalysis: Nonheme Fe Enzyme‐Catalyzed Enantioconvergent Radical Decarboxylative Azidation, Thiocyanation, and Isocyanation of Redox‐Active Esters

Angewandte Chemie, Volume 137, Issue 29, July 14, 2025.
Through the directed evolution of an underexploited nonheme Fe extradiol dioxygenase, we developed a unified cooperative photobiocatalytic strategy to allow for three types of enantioconvergent radical transformations, including azidation, thiocyanation, and isocyanation.

Evaluation of the nutritional value of sorghum grain for rainbow trout, Oncorhynchus mykiss and hybrid striped bass, Morone chrysops × Morone saxatilis

Journal of the World Aquaculture Society, Volume 56, Issue 4, August 2025.
Abstract Aquaculture feeds with optimum digestible starch levels can provide benefits but only through the continued identification and characterization of the available nutrient content of novel or lesser utilized starch sources for a larger variety of aquatic species.

From Amino Acids to α‐Keto Acids via β‐Elimination and Transamination Initiates a Pathway to Prebiotic Reaction Networks

Angewandte Chemie, Volume 137, Issue 29, July 14, 2025.
A reaction starting from two amino acids, phosphoserine and Gly, reveals a pathway to the α‐keto acid building blocks pyruvate and glyoxylate, key components of a plausible early metabolic system. A one‐pot β‐elimination and transamination sequence also initiates a cascade of protometabolic transformations that provide crucial insights into the ...

POET CFP, a corn‐fermented protein concentrate, as a potential novel aquafeed ingredient for juvenile European sea bass, Dicentrarchus labrax

Journal of the World Aquaculture Society, Volume 56, Issue 4, August 2025.
Abstract This study evaluated POET CFP, a corn‐fermented protein derived from dry‐mill bioethanol production, as a potential candidate for use in European seabass aquafeeds. The apparent digestibility coefficients (ADC) of POET CFP were evaluated and compared to soybean meal.

Old player, new roles: defining the role of the plastidial phosphorylase

New Phytologist, Volume 247, Issue 4, Page 1622-1632, August 2025.
Summary The plastidial phosphorylase (Pho1 or Phs1; E.C. 2.4.1.1) is a ubiquitous enzyme among plants that catalyzes the formation and degradation of glucans. Although the first report connecting Pho1 with starch metabolism came out > 80 years ago, its precise role is still a matter of debate.
