β-galactosidase-specific band shifts were not observed in monocots and basal angiosperms samples.

open access: yes, 2023
(A) Tomato fruits produced GBGM oligo after AnGH5 digestion, which migrated to GAGM after the following β-galactosidase treatment. M: marker lane (standard oligo saccharides).

Reversible Control of Enzymatic Transglycosylations in Supercritical Fluoroform Using a Lipid-Coated β-d-Galactosidase

open access: yes, 2016
The transgalactosylation rate catalyzed by the lipid-coated β-d-galactosidase in supercritical fluoroform (scCHF3) can be reversibly controlled by changing temperature or pressure (reflecting polarity changes) without damaging ...

Genome-Wide Analysis of β-Galactosidases in Xanthomonas campestris pv. campestris 8004

open access: yesFrontiers in Microbiology, 2018
Bacterial β-galactosidase is involved in lactose metabolism and acts as a prevalent reporter enzyme used in studying the activities of prokaryotic and eukaryotic promoters. Xanthomonas campestris pv.

Expression of β-galactosidase inRhizobium japonicum [PDF]

open access: yesFEMS Microbiology Letters, 1985
The plasmid pGC91.14 was used to introduce via conjugation the Escherichia coli lac operon into fast-growing and slow-growing strains of Rhizobium japonicum. Exconjugants now expressed higher levels of β-galactosidase activity which was still inducible by isopropyl-β-d-thiogalactoside (IPTG).

Transcriptional analysis of the β-galactosidase gene (pbg) inClostridium perfringens [PDF]

open access: yesFEMS Microbiology Letters, 1995
The mode of expression of the beta-galactosidase gene (pbg) of Clostridium perfringens was examined. The pbg gene was transcribed on a single 3.7-kb mRNA. The transcript contained a message for ORF54, located upstream of the pbg gene in the chromosome, indicating that ORF54 and the pbg gene comprise one operon (pbg operon). Expression of the pbg operon

Thermostable α-galactosidase fromBacillus stearothermophilusNUB3621: cloning, sequencing and characterization [PDF]

open access: yesFEMS Microbiology Letters, 1999
An alpha-galactosidase gene from the thermophilic bacterium Bacillus stearothermophilus NUB3621 was cloned, sequenced, expressed in Escherichia coli and the recombinant protein was purified. The Bacillus enzyme, designated AgaN, is similar to alpha-galactosidases of family 36 in the classification of glycosyl hydrolases.

Anaerobic expression of thegyrAgene demonstrated by β-galactosidase activity ingyrA::Mu-lacfusion derivatives ofEscherichia coli [PDF]

open access: yesFEMS Microbiology Letters, 1988
E. coli C600Δ lac was infected with a Mu- lac defective phage. Lysogens resistant to ampicillin (25 µg/ml) and nalidixic acid (20 µg/ml) were unable to grow anaerobically and insensitive to nalidixic acid (150 µg/ml), indicating formation of gyrA ::Mu- lac fusions.

Experimental conditions may affect reproducibility of the beta-galactosidase assay [PDF]

open access: yesFEMS Microbiology Letters, 1992
Several experimental conditions and parameters contributing to the determination of beta-galactosidase activity, as proposed in Miller's assay, were studied. Use of the absorbance correction factor and the nature and concentration of permeabilizing agents were taken into account as different experimental conditions.

Cloning of the phospho-β-galactosidase gene inEscherichia colifrom lactose-negative mutants ofStreptococcus mutansisolated following random mutagenesis with plasmid pVA891 clone banks [PDF]

open access: yesFEMS Microbiology Letters, 1992
In order to mutagenize Streptococcus mutans a marker rescue plasmid, pVA891, was employed. The plasmid was ligated with Sau3AI digested chromosomal DNA fragments from S. mutans GS-5IS3 and the resultant plasmids were amplified in Escherichia coli.

A data comparison between a traditional and the single-step β-galactosidase assay

open access: yesData in Brief, 2016
This article describes reproducibility of a single-step automated β-galactosidase, and the equivalence of its data to the traditional assay (“Experiments in Molecular Genetics” [1]).
