Overexpression of Transketolase Relieves xylA Repression and Enhances Xylose Utilization in Saccharomyces cerevisiae During Mixed Sugar Fermentation

GCB Bioenergy, Volume 17, Issue 7, July 2025.
To overcome the bottleneck of inefficient xylose utilization in lignocellulosic bioethanol production, we constructed a recombinant Saccharomyces cerevisiae strain (INVSc‐xylA‐Xltr1p‐TKL1) by overexpressing the transketolase gene TKL1. This engineering strategy significantly enhanced xylose consumption by 33%, upregulated xylose isomerase (xylA ...

Prevalence and Whole Genome Sequence Analysis of Mycoplasma bovis Isolates From Bulk Tank Milk of Dairy Farms in Tennessee, USA

Journal of Veterinary Internal Medicine, Volume 39, Issue 4, July/August 2025.
ABSTRACT Background Mycoplasma bovis mastitis is an important disease of dairy cows that causes substantial economic losses. However, its prevalence in different states in the United States (US), including Tennessee, is not well known. Furthermore, recent studies showed a high prevalence of bovine hemotropic mycoplasmas in US dairy farms.

Multiple transitions to high l‐DOPA 4,5‐dioxygenase activity reveal molecular pathways to convergent betalain pigmentation in Caryophyllales

New Phytologist, Volume 247, Issue 1, Page 341-357, July 2025.
Summary Many specialized metabolic pathways have evolved convergently in plants, but distinguishing multiple origins from alternative evolutionary scenarios can be difficult. Here, we explore the evolution of l‐3,4‐dihydroxyphenylalanine (l‐DOPA) 4,5‐dioxygenase (DODA) enzymes to better resolve the convergent evolution of the betalain biosynthetic ...

A Method for Constructing Nucleosome Arrays with Spatially Defined Histone PTMs and DNA Damage

Angewandte Chemie, Volume 137, Issue 24, June 10, 2025.
This work advances methodology by addressing challenges in mimicking the complex in vivo spatial relationships of histone acetylation and DNA damage. The combination of an abiotic/enzymatic hybrid catalyst system (ABEHCS) and the plug‐and‐play method has constituted a versatile platform to construct nucleosome arrays with precise histone acetylation ...
