A Multistate Adaptive System of Topologically Distinct Chiral Assemblies

open access: yesAngewandte Chemie International Edition, Accepted Article.
Biological systems exemplify the extraordinary adaptability of living organisms to their surroundings, demonstrating the capacity to reconfigure their structure, properties, and function in response to specific environmental signals. In this context, the exploration of multistate chemical systems designed to mimic natural counterparts, with the ...

The structural basis for specific decoding of AUA by isoleucine tRNA on the ribosome

open access: yesNature Structural &Molecular Biology, 2013
Decoding of the AUA isoleucine codon in bacteria and archaea requires modification of a C in the anticodon wobble position of the isoleucine tRNA. Here, we report the crystal structure of the archaeal tRNA2Ile, which contains the modification agmatidine ...

Green and Sustainable Production of Edible Pullulan/Whey Nanofibers Loaded With Black Cumin (Nigella sativa) Waste Extract

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT In this study, the electrospinning method was used to create green synthesis sustainable pullulan and whey protein nanofibers loaded with black cumin waste extract. FE‐SEM imaging, FTIR, XRD, DSC, total phenolic content determination, total antioxidant activity determination, and antibacterial activity assessment were used to characterize the ...

Cytochromes P450 CYP94C1 and CYP94B3 Catalyze Two Successive Oxidation Steps of Plant Hormone Jasmonoyl-isoleucine for Catabolic Turnover

open access: yesJournal of Biological Chemistry, 2012
Background: Oxidized derivatives of the plant hormone jasmonoyl-isoleucine accumulate in wounded Arabidopsis leaves. Results: Cytochromes P450 CYP94C1 and CYP94B3 cooperate to catalyze the formation of 12OH-JA-Ile and 12COOH-JA-Ile.

Effects of Dietary Protein Level on Growth Performance, Serum Biochemistry, Intestinal Morphology, and Intestinal Microbiota in Ningxiang Finishing Pigs

open access: yesAnimal Research and One Health, EarlyView.
A low‐protein (LP) diet maintained growth performance while enhancing colonic microbiota composition and nitrogen utilization in Ningxiang finishing pigs. These findings enhance our understanding of protein nutrition in indigenous fat‐type pig breeds and provide a theoretical foundation for optimizing dietary formulations in Ningxiang pigs.

Dietary supplement of sodium butyrate improves the growth performance and intestinal health by targeting Wnt/β‐catenin signaling pathway in rabbits

open access: yesAnimal Research and One Health, EarlyView.
Dietary supplement of sodium butyrate, may relate to regulating intestinal health and thus the growth performance and meat quality of rabbits by regulating the continuous process of promoting the periodic cycle of cecal epithelial cells. Abstract Supplementation of sodium butyrate (SB) has been proved to be beneficial for improving the growth ...

Isoleucine and leucine independently regulate mTOR signaling and protein synthesis in MAC-T cells and bovine mammary tissue slices.

open access: yesJournal of NutriLife, 2012
Understanding the regulatory effects of individual amino acids (AA) on milk protein synthesis rates is important for improving protein and AA requirement models for lactation. The objective of this study was to examine the effects of individual essential

Ubiquitin C‐Terminal Hydrolase L1 (UCHL1), Beyond Hydrolysis

open access: yesBioEssays, EarlyView.
UCHL1 is a neuron‐enriched component of the ubiquitin‐proteasome system. This review debates the biological relevance of its biochemical roles: limited DUB activity, potential ligase function, and mono‐ubiquitin stabilization. We emphasize the need to clarify the mechanisms and identify natural substrates for each function to understand their role in ...
