Onecut-dependent Nkx6.2 transcription factor expression is required for proper formation and activity of spinal locomotor circuits. [PDF]

, 2020
In the developing spinal cord, Onecut transcription factors control the diversification of motor neurons into distinct neuronal subsets by ensuring the maintenance of Isl1 expression during differentiation.

High gene expression inEscherichia coliof recombinant alginate lyase as a fused protein with β-galactosidase α-peptide [PDF]

FEMS Microbiology Letters, 1995
Escherichia coli LE392 (pAL28) was previously isolated as a positive clone harboring the alginate lyase gene (aly) from an alginate-degrading strain, Pseudomonas sp. OS-ALG-9. The plasmid pAL205, one of the constructs obtained after successive subcloning of pAL28, gave the highest expression of aly in E. coli cells.

Effect of yeast extract supplementation on β-galactosidase activity of Lactobacillus delbrueckii subsp. bulgaricus 11842 grown in whey.

Czech Journal of Food Sciences, 2001
Lactobacillus delbrueckii subsp. bulgaricus 11842 (LB 11842) was grown in reconstituted sweet whey supplemented with 0 to 1% yeast extract. The β-galactosidase activity was determined from the hydrolysis of o-nitrophenyl- β-D-galactopyranoside (ONPG) by ...

Invited review: Properties of β-galactosidases derived from Lactobacillaceae species and their capacity for galacto-oligosaccharide production

Journal of Dairy Science, 2023
: β-galactosidase (enzymatic class 3.2.1.23) is one of the dairy industry's most important and widely used enzymes. The enzyme is part of a large family known to catalyze hydrolysis and transglycosylation reactions.

Antigenicity of a viral peptide displayed on β-galactosidase fusion proteins is influenced by the presence of the homologous partner protein [PDF]

FEMS Microbiology Letters, 1996
Several beta-galactosidase fusion proteins have been constructed containing the entire VP1 protein from foot-and-mouth disease virus (FMDV) [Corchero et al. (1996) J. Biotechnol. in press]. The antigenicity of the major immunodominant site A (13 amino acids in length) within the VP1 protein has been studied in competitive ELISA using a panel of seven ...

Construction of a flocculent Saccharomyces cerevisiae strain secreting high levels of Aspergillus niger β-galactosidase [PDF]

, 2002
A flocculent Saccharomyces cerevisiae strain secreting Aspergillus niger β-galactosidase activity was constructed by transforming S. cerevisiae NCYC869-A3 strain with plasmid pVK1.1 harboring the A. niger β-galactosidase gene, lacA, under the control

ALGINATE COATED MgO-NPs IMPROVES THE STABILITY OF Kluyveromyces lactis β-GALACTOSIDASE FOR BIOTECHNOLOGICAL APPLICATIONS

Química Nova, 2023
The current study was undertaken to immobilize Kluveromyces lactis β-galactosidase on alginate coated magnesium oxide nanoparticles (ACMONPs). Transmission electron microscopy showed that MgO-NPs synthesized by wet chemical approach were of 27 nm size ...

Identification of bacteria with β-galactosidase activity in faeces from lactase non-persistent subjects [PDF]

FEMS Microbiology Ecology, 2005
Previous studies suggest that, besides the maldigestion of lactose in the small intestine, the colonic processing of lactose might play a role in lactose intolerance. beta-Galactosidase is the bacterial enzyme which catalyzes the first step of lactose fermentation in the colon.

Lactobacillus fermentumCRL 722 is able to deliver active α-galactosidase activity in the small intestine of rats [PDF]

FEMS Microbiology Letters, 2005
alpha-galactooligosaccharides (alpha-GOS) found in legumes such as soybeans can cause gastrointestinal disorders since mammals lack alpha-galactosidase (alpha-Gal) in the small intestine which is necessary for their hydrolysis. Lactobacillus fermentum CRL 722 is a lactic acid bacterium (LAB) capable of degrading alpha-GOS due to its elevated alpha-Gal ...
