Plasma α-galactosidase A: Properties and comparisons with tissue α-galactosidases
Biochimica et Biophysica Acta (BBA) - Enzymology, 1978The human plasma form of alpha-galactosidase A (alpha-D-galactoside galactohydrolase, EC 3.2.1.22) was highly purified and exhibited apparent Km values of 1.9 mM with 4-methylumbelliferyl-alpha-D-galactopyranoside and 0.23 mM with globotriglycosylceramide.

The discovery of β-galactosidase
Trends in Biochemical Sciences, 1989The enzyme beta-galactosidase was first mentioned in the literature by Beijerinck exactly a hundred years ago. The Department of Microbiology and Enzymology of the Delft University of Technology keeps the memory of Beijerinck, its first professor, alive by maintaining a 'Beijerinck-room' in the attic of the building.

A sensitive micro-immunoassay using β-galactosidase/ anti-β-galactosidase complexes
Journal of Immunological Methods, 1987This paper describes a new sensitive microELISA based on enzyme/anti-enzyme complexes following an unlabelled antibody bridging step. beta-Galactosidase/anti-beta-galactosidase complexes were made using a monoclonal antibody raised against bacterial (E. coli) beta-galactosidase and enzyme activity was quantified with a fluorogenic substrate. Because of

Publisher Summary The enzyme β-galactosidase is one of several oligosaccharide-splitting enzymes that have been purified and subsequently characterized to varying degrees both physically and mechanistically. It is found in a wide range of biological sources in both the plant and animal kingdoms, although the principal source of study has been in the ...

Publisher Summary The α-galactosidase from the coffee bean is one of the few capable of hydrolyzing the nonreducing terminal α-D-galactopyranosyl residue of blood group B antigens. As part of the studies on the structure of these antigens in human erythrocytes, a method has been developed for the rapid and complete purification of the enzyme in high ...

Publisher Summary This chapter presents information on the chemistry and enzymology of β-galactosidases. β-Galactosidases have been found in numerous microorganisms, animals, and plants. Tests for fermentation of lactose play an important role in diagnostic bacteriology of Enterobacteriaceae, so the occurrence of β-galactosidase in gram-negative rods
