The Plant Journal, Volume 127, Issue 4, August 2026.SUMMARY Alternative splicing (AS) is a common gene regulatory mechanism involving distinct interactions between trans‐acting factors and cis‐regulatory elements on the precursor messenger RNA (pre‐mRNA). In this study, we have functionally characterized the structured motif 45ABC, which is located in the pre‐mRNAs of RNA‐binding protein (RBP) 45 genes ...

Sulfadiazine selection enables high‐efficiency transformation in Nannochloropsis and Microchloropsis
The Plant Journal, Volume 127, Issue 3, August 2026.SUMMARY Nannochloropsis and Microchloropsis are important as eustigmatophyte model organisms and the production of high‐value lipids. Efficient selectable markers are indispensable for genetic engineering to study and improve production yield of these species.

ChemBioChem, Volume 27, Issue 13, 14 July 2026.A whole‐cell biocatalytic cascade in engineered Escherichia coli RARE couples the ω‐transaminase from Pseudomonas psychrotolerans with pyruvate decarboxylase from Zymomonas mobilis to shift transamination toward amine formation via pyruvate removal. Integration of the cascade into a chemo‐enzymatic synthesis pathway enables the scalable production of 2,

The wide phenotypic spectrum of thiamine metabolism dysfunction syndrome 5 and its treatment
Orphanet Journal of Rare DiseasesThiamine metabolism dysfunction syndrome 5 (TMDS5) is a rare inborn error of metabolism caused by variants in TPK1, leading to reduced TPK levels. This enzyme is crucial for the production of thiamine pyrophosphate, the active form of thiamine, a vital ...

Enzymic formation of thiamine pyrophosphate in plants.
Journal of Nutritional Science and Vitaminology, 1975 Evidence was presented by paper chromatographic analysis on the occurrence of an enzyme capable of catalyzing a pyrophosphate transfer from ATP to thiamine in green leaves of various plants. The exclusive localization of the enzyme activity in the 105,000 X g supernatant (in a soluble form) was demonstrated by differential centrifugation of a cell ...

Oxidative decarboxylation of retinoic acid in microsomes of rat liver and kidney
Journal of Lipid Research, 1968 Liver and kidney microsomes have been found to catalyze a rapid decarboxylation of retinoic acid in vitro. The reaction requires NADPH and Fe2+, and is further stimulated by the presence of pyrophosphate.

Thiamine deficiency in alcoholics with normal body mass index
Journal of Dr. NTR University of Health Sciences, 2019 Background: Ethanol consumption leads to nutritional deficiency due to various causes. Well known theoretical as well as literature supports the hypothesis on dietary factors, metabolic derangement and alcohol per se produces empty calories.
