Porungo cheese whey: a new substrate to produce β-galactosidase [PDF]
The bioconversion of porungo cheese whey to produce β-galactosidase in batch system was studied. The whey released after curd cutting and precipitation during porungo cheese production was collected in borosilicate flasks.

Optimization of β-galactosidase production from lactic acid bacteria [PDF]
β-galactosidase, commonly known as lactase, represents commercially important enzyme that is prevalently used for lactose hydrolysis in milk and whey. To the date, it has been isolated from various sources.

A food-grade vector for Streptococcus thermophilus based on the α-complementation of β-galactosidase
: Streptococcus thermophilus is a common yogurt starter that consumes lactose as its primary carbon source. The enzyme β-galactosidase is essential for the lactose metabolism and the growth of this species.

Effect of β-Mannanase and α-Galactosidase Supplementation to Soybean Meal Based Diets on Growth, Feed Efficiency and Nutrient Digestibility of Rainbow Trout, (Walbaum) [PDF]
A 12-week feeding trial was conducted with 87 g rainbow trout to evaluate the effects on growth performances, feed efficiency and nutrient digestibility of adding β-mannanase and α-galactosidase enzymes, solely or in combination.

Effect of tunicamycin on α-galactosidase secretion byAspergillus nidulansand the importance ofN-glycosylation [PDF]
Aspergillus nidulans released α-galactosidase into the culture medium during the exponential growth on either lactose or galactose as the only carbon source. This enzyme is a glycoprotein. Its treatment with endoglycosidases produces a reduction in its molecular mass but the resulting enzyme conserved some of their carbohydrate components in addition ...

Thermostable α-galactosidase fromThermotoga neapolitana: cloning, sequencing and expression [PDF]
A gene encoding a thermostable alpha-galactosidase from the hyperthermophile Thermotoga neapolitana was cloned and sequenced. Sequence analysis showed that the 552-amino acid protein is similar to Escherichia coli Raf type alpha-galactosidase and belongs to Family 36 of the glycosyl hydrolases. Recombinant alpha-galactosidase expressed in E. coli has a

Yersinia pestis lacZexpresses a β-galactosidase with low enzymatic activity [PDF]
Although very little, if any, beta-galactosidase activity is detected in Yersinia pestis by a standard Miller assay, we found that Y. pestis KIM6+ cells formed blue colonies on plates containing 5-bromo-4-chloro-3-indolyl-beta-D-galactoside (X-gal). Searches of the Y.

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

Different domains cooperate to target the human ribosomal L7a protein to the nucleus and to the nucleoli. [PDF]
The human ribosomal protein L7a is a component of the major ribosomal subunit. We transiently expressed in HeLa cells L7a-β-galactosidase fusion proteins and studied their subcellular localization by indirect immunofluorescence staining with anti-β ...
