lower beta-glucuronidase activity is significantly associated with higher intakes of calcium, iron, and magnesium. Several dietary and nondietary factors are associated with beta-glucuronidase activity. The botanical families Cruciferae, Rutaceae, Compositae, Roseaceae, and Umbelliferae might decrease the enzyme activity when being part of the diet

adsorption of beta-glucuronidase on biopolymers is studied by the retention of the enzyme on the membrane of a concentrator with a pore diameter of 300 kDa and by native PAGE. Pectin-protein complexes (fractions PPC/CP and PPC/C) are established to increase the activity of beta-glucuronidase by 50 and 100%, respectively. There is a positive correlation between the increase of beta-glucuronidase activity in the presence of carbohydrates and enzyme adsorption on the polymers. The activity of the enzyme in the gel after electrophoresis of the PPC/+ beta-glucuronidase mixture is inversely proportional to the concentration of PPC/C in the mixture

both the placental 80000 Da and 64000 Da peptides, though not the 18000 Da one, are apparently phosphorylated, whereas the enzyme of leukemic cells is poorly phosphorylated
proteolytic modification
-
human beta-glucuronidase remains intracellular in BHK cells after synthesis undergoes a proteolytic processing event, i.e. a reduction in mass of 3000-4000 Da
proteolytic modification
-
the 80000 Da form is a protein from which a 22000 amino-acid-N-terminal signal peptide has been removed. A second cleavage occurs between the 159th and 160th amino acid to produce the 64000 Da and 18000 Da polypeptides. Thus the 18000 Da polypeptide of 137 amino acids represents the N-terminal part of the 80000 Da precursor

additional information
-
the enzyme is engineered as fusion with an N-terminal 76 amino acid ubiquitin-coding region. When translated in any eukaryotic cell, such ubiquitin fusions are cleaved by ubiqitin-specific proteases specifically after the C-terminus of ubiquitin, irrespective of the distal amino acid (with the exception of Pro), releasing the downstream protein with the specified amino terminus. The presence of an N-terminal uncleavable ubiquitin on GUS does not reduce activity. A version of GUS with phenylalanine at the mature N-terminus accumulates a minimum of 3fold lower than GUS with methionine at its mature N-terminus

additional information
-
in the mutant enzyme a stop codon is introduced after the CAC/His-637 codon, thereby eliminating 14 amino acids from the C-terminus. Thereby the last Cys at position 644 is eliminated. In the mutant, covalent linkage between two monomers is no longer observed, indicating that Cys44 is involved in intermolecular disulfide-bond formation

-
enzymatic assay adapted to study the fate of fecal coliforms in survival experiments, and appears to be rapid and efficient way to estimate the microbiological quality of surface waters. The major advantage of the enzymtic assay is the very short time response, and thus this method offers a powerful, rapid, and efficient way to estimate the microbiological quality of bathing and fishing areas, and to monitor disinfection efficiencies
analysis
-
reporter enzyme which is used for studies in higher plants because endogenous activities are low and sensitive assays are available. A version of GUS with phenylalanine at the mature N-terminus accumulates a minimum of 3fold lower than GUS with methionine at its mature N-terminus. This altered protein can be useful for promoter studies which require more rapid changes in the accumulation of the reporter protein
analysis
-
comparison of commercially available kits to assess water quality and evaluation of their ability to detect Escherichia coli. Chromocult, MI agar, Readycult, and Colilert detect beta-glucuronidase production from respectively 79.9, 79.9, 81.1, and 51.4% of the 74 Escherichia coli strains tested. These four methods detect beta-galactosidase production from respectively 85.1, 73.8, 84.1, and 84.1% of the total coliform strains tested. The high level of false-negative results for Escherichia coli recognition obtained by all four methods suggests that they may not be appropriate for identification of presumptive Escherichia coli strains
analysis
-
comparison of commercially available kits used for the simultaneous detection of coliforms and Escherichia coli from water. Membrane lactose glucuronide agar, Colilert-18, MI agar, Colitag and Chromocult agar to detect beta-D-glucuronidase activity are tested with over 1000 isolates of Escherichia coli recovered from naturally contaminated water samples. Four of the media give very similar results but membrane lactose glucuronide agar fails to detect glucuronidase activity in 15.6% of the cultures tested
analysis
-
precise and reliable detection of Escherichia coli strains for differentiation from biochemically and ohylogenetically related bacteria. Method is based on polymerase chain reaction, in which four genes coding for lactose permease, cytochrome bd complex, beta-D-glucuronidase, and beta-D-galactosidase, serve as target DNA sequences

in environmental toxicology, techniques used to visualise lysosomes in order to determine their responses to pollutants are the lysosomal structural changes test and the lysosomal membrane stability test are based on the histochemical application of lysosomal marker enzymes. In mussel digestive cells, the marker enzymes used are beta-glucuronidase and hexosaminidase. beta-Glucuronidase, but not hexosaminindase, histochemistry provides an appropriate marker for the lysosomal structural changes test and that, although both lysosomal marker enzymes can be employed in the lysosomal membrane stability test, different values would be obtained depending on the marker enzyme employed
