Beta-galactosidase from Aureobasidium pullulans

Letters in Applied Microbiology, 1989
Aureobasidium pullulans is a new source of enzyme beta-galactosidase with optimum activity at pH 6·8 and a temperature of 45°C. Lactose induced enzyme synthesis, but low constitutive levels of enzyme were seen with other sugars. Addition of Mn2+ and Ca2+ increased enzyme production and activity. Co2+ was a strong activator of enzyme activity.

An acidophilic beta-galactosidase from Bispora sp. MEY-1 with high lactose hydrolytic activity under simulated gastric conditions.

Journal of Agricultural and Food Chemistry, 2009
BgalA, a full-length gene (3,009 bp) that encodes a beta-galactosidase, was cloned from the meso-acidophilic fungus Bispora sp. MEY-1 and expressed in Pichia pastoris. The deduced amino acid sequence of BgalA shares highest identity (55.5%) with the beta-

Adrenoleukodystrophy and beta-galactosidase deficiency: Patient and carrier

Journal of Neurology, 1986
A patient with adrenoleukodystrophy and his mother, a carrier, showed an elevated ratio of very long-chain fatty acids to long-chain fatty acids and decreased beta-galactosidase activity. Other lysosomal enzyme activities were normal except for the borderline level of arylsulfatase-A activity.

Beta-galactosidase immobilization on chitosan microspheres

Journal of Biotechnology, 2007
Application of solid-phase biocatalysts has become important during the last decades. Enzymes could be immobilized on various supports and by different methods. The properties of immobilized biocatalysts are influenced by the characteristics of enzyme, support material and the immobilization method.

Morquio-like syndrome with beta galactosidase deficiency and normal hexosamine sulfatase activity: mucopolysacchariodosis IVB.

American journal of medical genetics, 1977
A 14-year-old white girl with mild dysostosis multiplex, odontoid hypoplasia, short stature, cloudy corneas, keratansulfaturia, but without detectable central nervous system abnormalities was referred with the diagnosis of Morquio syndrome.

A quantitation of the factors which affect the hydrolase and transgalactosylase activities of beta-galactosidase (E. coli) on lactose.

Biochemistry, 1976
A study was implemented to quantitate the hydrolase and transgalactosylase activities of beta-galactosidase (E. coli) with lactose as the substrate and to investigate various factors which affect these activities.

Inactivation of .beta.-galactosidase by iodination of tyrosine-253

Biochemistry, 1982
Beta-Galactosidase is rapidly inactivated by iodination catalyzed by lactoperoxidase but is not inactivated in the presence of the substrate analogue, isopropyl beta-D-thiogalactoside (IPTG). Enzyme activity is lost upon the incorporation of 1 mol of iodine per mol of monomer, without dissociation of the tetrameric structure.

Creation of a Recombinant Bacteriophage to Express Beta-Galactosidase

2014
Human illness caused by the consumption of food contaminated with pathogenic bacteria is a worldwide problem that requires new detection methods to solve. The use of reporter bacteriophage as a device for detection of food-borne pathogens provides a promising new method to distinguish contaminated food and therefore prevent humans from infection ...

Neuronal-visceral GM1 gangliosidosis in a dog with beta-galactosidase deficiency.

Science, 1976
A 9-month-old dog with a history of progressive motor dysfunction was shown to have a deficiency in brain beta-galactosidase activity. The canine disease, like that of children with GM1 gangliosidosis, is characterized by accumulation of GM1 ganglioside ...
