Purification and molecular properties of an α-galactosidase synthesized and secreted byAspergillus nidulans [PDF]

FEMS Microbiology Letters, 1993
alpha-Galactosidases from mycelial extract and culture filtrate of Aspergillus nidulans have been purified to homogeneity and utilised to obtain polyclonal antibodies anti-alpha-galactosidase. The enzymatic characteristics and the cross reactivity of the antibodies suggest that alpha-galactosidases isolated from the two sources were the same enzyme ...

Ileocecal appendix involvement in fabry disease mimicking an acute abdomen [PDF]

, 2014
Anderson-Fabry disease (AFD) is a rare, X-linked, lysosomal storage disorder due to a deficiency of alphagalactosidase A. The direct consequence is a lipid storage with the accumulation of glycosphingolipids throughout the body.

Identification of an intestine-specific promoter and inducible expression of bacterial α-galactosidase in mammalian cells by a lac operon system

Journal of Animal Science and Biotechnology, 2012
Background α-galactosidase has been widely used in animal husbandry to reduce anti-nutritional factors (such as α-galactoside) in feed. Intestine-specific and substrate inducible expression of α-galactosidase would be highly beneficial for transgenic ...

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

FEMS 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]

FEMS 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.

Characterization and molecular cloning of a heterodimeric β-galactosidase from the probiotic strainLactobacillus acidophilusR22 [PDF]

FEMS Microbiology Letters, 2007
Beta-galactosidase from the probiotic strain Lactobacillus acidophilus R22 was purified to apparent homogeneity by ammonium sulphate fractionation, hydrophobic interaction, and affinity chromatography. The enzyme is a heterodimer consisting of two subunits of 35 and 72 kDa, as determined by gel electrophoresis.

Is it Fabry disease? Diagnostic and follow-up approach [PDF]

, 2016
A doença de Anderson-Fabry (DAF) é uma doença sistémica de sobrecarga lisossomal causada por mutações patogénicas do gene GLA (cromossoma X) que condicionam diminuição ou ausência α-galactosidase A e acumulação de globotriaosilceramida (Gb3) e outros ...

α-Galactosidase A fromPseudomonas fluorescenssubsp.cellulosa: cloning, high level expression and its role in galactomannan hydrolysis [PDF]

FEMS Microbiology Letters, 2000
A library of Pseudomonas fluorescens subsp. cellulosa genomic DNA, constructed in lambda ZAPII, was screened for alpha-D-galactosidase activity. The DNA inserts from six galactosidase-positive clones were rescued into plasmids. Restriction digestion and Southern analysis revealed that each of the plasmids contained a common DNA sequence.

Identification and biotechnological characterization of lactic acid bacteria isolated from chickpea sourdough in northwestern Argentina [PDF]

, 2019
Chickpea, a relevant legume worldwide, can be nutritional and functionally improved by fermentation with lactic acid bacteria (LAB). In order to select suitable autochthonous starter cultures, we isolated and identified LAB from kabuli chickpeas ...

TNF receptor–related factor 3 inactivation promotes the development of intrahepatic cholangiocarcinoma through NF‐κB‐inducing kinase–mediated hepatocyte transdifferentiation

Hepatology, EarlyView., 2022
Abstract Background and Aims Intrahepatic cholangiocarcinoma (ICC) is a deadly but poorly understood disease, and its treatment options are very limited. The aim of this study was to identify the molecular drivers of ICC and search for therapeutic targets.
