From a series of rapid quench kinetic experiments, it has been demonstrated that muscle D-fructose bisphosphate aldolase catalyzes the cleavage of beta-D-fructose 1,6-bisphosphate but not that of the alpha anomer, although the alpha anomer may be tightly bound. Yeast D-fructose bisphosphate aldolase appears to utilize both alpha and beta anomers of the substrate, with yeast apoaldolase catalyzing the interconversion of the alpha and beta forms.

Pruning is a common forest-tending method; its purpose is to promote growth and improve the overall stand quality. Poplar is a fast-growing, broad-leaved tree species with high ecological and economic value. It is a common management method to promote its growth by pruning and adjusting the spatial structure of the stand, but its potential regulatory mechanism remains unclear.

Article Synopsis
- * Using a metabolomics approach, researchers analyzed serum metabolites in 30 stable COPD patients and identified 25 metabolites that differed significantly between those with frequent and non-frequent exacerbations, affecting lipid, energy, amino acid, and immune pathways.
- * The study found specific metabolites like D-fructose 1,6-bisphosphate and arginine could effectively distinguish between COPD-FE and COPD non-frequent exacerbators, with high accuracy in distinguishing groups confirmed in an external cohort of 20 patients.
The role of afforestation with diverse woody species in enhancing and restructuring the soil microenvironment in polymetallic coal gangue dumps.

To elucidate the effects of long-term (20 years) afforestation with different woody plant species on the soil microenvironment in coal gangue polymetallic contaminated areas. This study analyzed the soil physicochemical properties, soil enzyme activities, soil ionophore, bacterial community structure, soil metabolite, and their interaction relationships at different vertical depths. Urease, sucrase, and acid phosphatase activities in the shallow soil layers increased by 4.

4-Hydroxy-2,5-dimethyl-3 (2H)-furanone (HDMF) is widely used in the food industry as a spice and flavoring agent with high market demand. In this study, fructose-1,6-bisphosphate aldolase (FBA) and triose phosphate isomerase (TPI) were overexpressed in in the form of single and double genes, respectively, via electroporation. High-yield HDMF-engineered yeast strains were constructed by combining the analysis of gene expression levels obtained by real-time fluorescence quantitative PCR technology and HDMF production measured by HPLC.
