Classification of polyphenol oxidases shows ancient gene duplication leading to two distinct enzyme types

iScience
Summary: Polyphenol oxidases (PPOs) are coupled binuclear copper proteins that catalyze the oxidation of phenols. New functions of PPOs are continuously being discovered, latest with several fungal o-methoxy phenolases, which are active on lignin-derived

RSM–ANFIS‐Based Process Optimization of Thermo‐Sonication of Amla Juice: Effect on Enzyme Inactivation, Physico‐Chemical, Phytochemical, Sensory, and Microbiological Quality

Food Chemistry International, EarlyView.
Thermo‐sonication parameters were optimized to maximize PPO inactivation while maintaining overall juice quality. ANFIS demonstrated superior predictive accuracy with higher R2 and lower RMSE compared to RSM. Further, the quality assessment of treated juice highlighted the potential of thermo‐sonication as a sustainable alternative to conventional ...

Acid-Adapted Polyphenol Oxidases from Agricultural Wastes: Extraction, Characterization, and Application in Plant Protein Crosslinking

Foods
Polyphenol oxidases (PPOs) are enzymes that oxidize mono- and diphenolic compounds to o-quinones, facilitating pigment formation and protein crosslinking in food systems, thereby improving their techno-functional properties.

Cloning, Expression, and Characterization of Prophenoloxidases from Asian Corn Borer, Ostrinia furnacalis (Gunée)

Journal of Immunology Research, 2016
Insect phenoloxidase (PO) belongs to the type 3 copper protein family and possesses oxidoreductase activities. PO is typically synthesized as a zymogen called prophenoloxidase (PPO) and requires the proteolytic activation to function. We here cloned full-

The research progress in polyethylene oxide polymer electrolytes

FlexMat, EarlyView.
Polyethylene oxide (PEO) has become the mainstream matrix material for solid polymer electrolytes (SPEs) due to its excellent lithium salt complexation ability and processability. However, its high crystallinity results in low ionic conductivity at room temperature and difficulty in suppressing lithium dendrite growth, which significantly hinders the ...

Guidelines for Immunomodulatory Assays of Food Bioactives on Drosophila melanogaster Model

Future Postharvest and Food, EarlyView.
Guidelines are proposed for evaluating the immunomodulatory effects of food bioactives in Drosophila melanogaster, involving treatment with bioactives, pathogen preparation, infection routes, and immune response assessment. This model highlights the conserved mechanisms of cellular and humoral immunity for studying host‐microbe interactions.

Euploidy rate and pregnancy outcomes in preimplantation genetic testing for aneuploidy cycles using progestin-primed ovarian stimulation versus GnRH antagonist protocol

Reproductive Biology and Endocrinology
Background Previous studies has yielded contradictory findings regarding the relationship between controlled ovarian hyperstimulation (COH) protocol and euploid blastocyst rate. This study aimed to investigate whether progestin-primed ovarian stimulation

Image_1_The Comparison of Fixed and Flexible Progestin Primed Ovarian Stimulation on Mature Oocyte Yield in Women at Risk of Premature Ovarian Insufficiency.tiff

, 2022
While gonadotrophin releasing hormone (GnRH) antagonists have been the standard of pituitary suppression during ovarian stimulation for ART, progestin primed ovarian stimulation (PPOS) has emerged as an alternative.

Optimized Copper Pretreatment Protocols for Premium Green Raisin Production via Vacuum Impregnation and Metallo‐Complex Stabilization

Future Postharvest and Food, EarlyView.
ABSTRACT Green raisin production is limited by rapid chlorophyll degradation during drying. This study evaluated copper metallo‐complex formation to stabilize green pigmentation in Vitis vinifera cv. Thompson Seedless grapes. Pretreatments with copper sulfate (CuSO4) pentahydrate (2%–6% w/v) were applied via dipping and vacuum impregnation (2–10 min ...
