Molecular basis of isozyme formation of beta-galactosidases in Bacillus stearothermophilus: isolation of two beta-galactosidase genes, bgaA and bgaB [PDF]
Bacillus stearothermophilus IAM11001 produced three beta-galactosidases, beta-galactosidase I, II, and III (beta-gal I, II, and III), which are detectable by polyacrylamide (nondenatured) gel electrophoresis. By connecting restriction fragments of the chromosomal DNA to plasmid vectors, followed by transformation of Escherichia coli, two beta ...

Engineering the Future of Restorative Clinical Peripheral Nerve Surgery
What if damaged nerves could regenerate more effectively? This review unveils cutting‐edge strategies to restore nerve function, from biomaterial scaffolds and bioactive molecules to living engineered tissues. By accelerating axonal regrowth, preserving Schwann cells, and enhancing connectivity, these approaches are reshaping nerve repair—offering new ...

Concentrated beta-galactosidase and cell permeabilization from Saccharomyces fragilis IZ 275 for beta-galactosidase activity in the hydrolysis of lactose [PDF]
Abstract The cheese whey shows an organic nutrient charge that can be used to obtain metabolites of interest by biotechnology of microorganisms. Thus, fermentative processes for enzyme production, in particular beta-galactosidase becomes feasible. The enzyme plays an important role in the biotech food industry to obtain milk and dairy products with low

D‐galactose (D‐gal) induced inner ear hair cell senescence by inhibiting TFEB transcription. RONIN/HCF1 promotes TFEB transcription to prevent cochlear HCs from D‐gal‐induced senescence through autophagy activation. Abstract Age‐related hearing loss is characterized by senescent inner ear hair cells (HCs) and reduced autophagy.

General Properties of Beta-Galactosidase of Xanthomonas campestris [PDF]
Partially purified β-galactosidase of Xanthomonas campestris required 32 to 37 C and pH 5.5 to 5.8 for optimum activity. The enzyme had low affinity for lactose hydrolysis ( K m = 22 mM) and was inhibited by thiol group reagents ...

This study reveals histone lactylation as a metabolic‐epigenetic regulator countering cellular senescence and skeletal muscle aging. Reduced lactylation impairs cell cycle, DNA repair and proteostasis pathways, while exercise restores glycolytic activity and lactylation levels, preserving muscle function.

Sialyl glycosides containing 4‐N‐derivatized sialic acids synthesized by a highly efficient one‐pot two‐enzyme (OP2E) chemoenzymatic sialylation strategy have been shown to be versatile probes. They can resist sialidase cleavage, be selective substrates by influenza sialidases, or be nanomolar substrate analog‐based inhibitors and affinity ligands ...

Inhibition of Ferroptosis Delays Aging and Extends Healthspan Across Multiple Species
This study identifies ferroptosis as a key driver of cellular senescence, with its inhibition delaying aging and extending healthspan across species. During senescence, ferroptosis worsens, increasing oxidative stress and lipid peroxidation, which accelerate aging.

Ethylene‐activated MdEAEL1 mediates the disassembly of the MdZFP3‐MdTPL4‐MdHDA19 transcriptional repression complex, upregulating the histone acetylation levels in the promoter regions of cell wall degradation‐related genes, consequently promoting softening during storage.

Thermostable Beta-Galactosidase from Fungi
Abstract Forty-five strains of molds were screened for beta-galactosidase activity. Strains exhibiting enzyme activity were evaluated for cell yield as well as enzyme units available per liter of the medium, per gram cell dry weight, and per milligram protein in their cell free extracts.
