Analysis of a novel gene and beta-galactosidase isozyme from a psychrotrophic Arthrobacter isolate.
We have characterized a new psychrotrophic Arthrobacter isolate which produces beta-galactosidase isozymes. When DNA from this isolate was transformed into an Escherichia coli host, we obtained three different fragments, designated 12, 14, and 15, each encoding a different beta-galactosidase isozyme. The beta-galactosidase produced from fragment 12 was of special interest because the protein su...
متن کاملMolecular basis of isozyme formation of beta-galactosidases in Bacillus stearothermophilus: isolation of two beta-galactosidase genes, bgaA and bgaB.
Bacillus stearothermophilus IAM11001 produced three beta-galactosidases, beta-galactosidase I, II, and III (beta-gal I, II, and III), which are detectable by polyacrylamide (nondenatured) gel electrophoresis. By connecting restriction fragments of the chromosomal DNA to plasmid vectors, followed by transformation of Escherichia coli, two beta-galactosidase genes (bgaA and bgaB) located close to...
متن کاملEffects of beta-lactam antibiotics on proliferating eucaryotic cells.
Most fungal toxins interact specifically with well-defined target structures, thereby reaching very high selectivity for the cell type attacked (17). The susceptibility of bacteria to beta-lactam antibiotics, as an example, is due to a number of penicillin-binding proteins on the bacterial plasma membrane. The eucaryotic cell lacks such target structures. Its insusceptibility to beta-lactams se...
متن کاملCharacterization of novel beta-galactosidase activity that contributes to glycoprotein degradation and virulence in Streptococcus pneumoniae.
The pneumococcus obtains its energy from the metabolism of host glycosides. Therefore, efficient degradation of host glycoproteins is integral to pneumococcal virulence. In search of novel pneumococcal glycosidases, we characterized the Streptococcus pneumoniae strain D39 protein encoded by SPD_0065 and found that this gene encodes a beta-galactosidase. The SPD_0065 recombinant protein released...
متن کاملHydrolysis of a novel lysosomotropic enzyme substrate for beta-galactosidase within intact cells.
With the goal of improving the detection of lysosomal sphingolipid hydrolases within intact cells, we have recently synthesized a new fluorophor, O-[4-(1-imidazolyl)butyl]-2,3-dicyano-1,4-hydroquinonyl beta-D-galactopyranoside (Im-DCH-beta-Gal). In the present study, we evaluated the interaction of Im-DCH-beta-Gal and its tetraacetate derivative, Im-DCH-beta-Gal(OAc)4, with living human fibrobl...
