Identification, Characterization, and Expression of a β-Galactosidase from Arion Species (Mollusca)
Biomolecules, 2022 β-Galactosidases (β-Gal, EC 3.2.1.23) catalyze the cleavage of terminal non-reducing β-D-galactose residues or transglycosylation reactions yielding galacto-oligosaccharides.

Thermostable α-galactosidase fromThermotoga neapolitana: cloning, sequencing and expression [PDF]
FEMS Microbiology Letters, 1998 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]
FEMS Microbiology Letters, 2006 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.

Transgalactosylation/Hydrolysis Ratios of Various β-Galactosidases Catalyzing Alkyl-β-Galactoside Synthesis in Single-Phased Alcohol Media [PDF]
Food Technology and Biotechnology, 2008 Three microbial galactosidases, Aspergillus oryzae, Escherichia coli and Kluyveromyces marxianus β-galactosidase, were used as catalysts for transgalactosylation synthesis of alkyl-β-galactosides in single-phased alcohol media.

Purification and molecular properties of an α-galactosidase synthesized and secreted byAspergillus nidulans [PDF]
FEMS Microbiology Letters, 1993 alpha-Galactosidases from mycelial extract and culture filtrate of Aspergillus nidulans have been purified to homogeneity and utilised to obtain polyclonal antibodies anti-alpha-galactosidase. The enzymatic characteristics and the cross reactivity of the antibodies suggest that alpha-galactosidases isolated from the two sources were the same enzyme ...

Thermostable β-galactosidases for the synthesis of human milk oligosaccharides [PDF]
, 2016 Human milk oligosaccharides (HMOs) designate a unique family of bioactive lactose-based molecules present in human breast milk. Using lactose as a cheap donor, some β-galactosidases (EC 3.2.1.23) can catalyze transgalactosylation to form the human milk ...

Expression of β-galactosidase inRhizobium japonicum [PDF]
FEMS Microbiology Letters, 1985 The plasmid pGC91.14 was used to introduce via conjugation the Escherichia coli lac operon into fast-growing and slow-growing strains of Rhizobium japonicum. Exconjugants now expressed higher levels of β-galactosidase activity which was still inducible by isopropyl-β-d-thiogalactoside (IPTG).

Transcriptional analysis of the β-galactosidase gene (pbg) inClostridium perfringens [PDF]
FEMS Microbiology Letters, 1995 The mode of expression of the beta-galactosidase gene (pbg) of Clostridium perfringens was examined. The pbg gene was transcribed on a single 3.7-kb mRNA. The transcript contained a message for ORF54, located upstream of the pbg gene in the chromosome, indicating that ORF54 and the pbg gene comprise one operon (pbg operon). Expression of the pbg operon

Thermostable α-galactosidase fromBacillus stearothermophilusNUB3621: cloning, sequencing and characterization [PDF]
FEMS Microbiology Letters, 1999 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.
