An alpha-galactosidase gene from Thermus brockianus ITI360 was cloned, sequenced, and expressed in Escherichia coli, and the recombinant protein was purified. The gene, designated agaT, codes for a 476-residue polypeptide with a calculated molecular mass of 53, 810 Da. The native structure of the recombinant enzyme (AgaT) was estimated to be a tetramer. AgaT displays amino acid sequence similarity to the alpha-galactosidases of Thermotoga neapolitana and Thermotoga maritima and a low-level… 

Identification and Molecular Characterization of a Novel Type of α-galactosidase from Pyrococcus furiosus

An α-galactosidase gene from Pyrococcus furiosus was identified, cloned and functionally expressed in Escherichia coli and it was concluded that glutamate 117 is the catalytic nucleophile, whereas the acid/base catalyst remains to be identified.

Characterization of two novel heat-active α-galactosidases from thermophilic bacteria

Two genes (agal1 and agal2) encoding α-galactosidases were identified by sequence-based screening approaches for high-temperature processes for the degradation of raffinose family oligosaccharides.

Cloning and characterization of a novel alpha-galactosidase from Bifidobacterium breve 203 capable of synthesizing Gal-alpha-1,4 linkage.

A novel alpha-galactosidase gene (aga2) was cloned from Bifidobacterium breve 203 and was capable of catalyzing transglycosylation as well as hydrolysis and catalyzing glycosyl transfer to various acceptors including monosaccharides, disaccharide and sugar alcohols.

Thermus thermophilus as source of thermozymes for biotechnological applications: homologous expression and biochemical characterization of an α-galactosidase

TtGalA is among the most thermoactive and thermostable α-galactosidases discovered so far, thus pointing to T. thermophilus as cell factory for the recombinant production of biocatalysts active at temperature values over 90 °C.

Characterization of Two New Glycosyl Hydrolases from the Lactic Acid Bacterium Carnobacterium piscicolaStrain BA

Three genes with homology to glycosyl hydrolases were detected on a DNA fragment cloned from a psychrophilic lactic acid bacterium isolate, Carnobacterium piscicola strain BA and activity on both α- and β-galactoside substrates decreased for cells grown with added glucose or lactose, but an increase in activity on a phosphorylated β-Galactosidase substrate was found for the cells supplemented with lactose.

Identification of a Novel α-Galactosidase from the Hyperthermophilic Archaeon Sulfolobus solfataricus

These Sulfolobus enzymes not only constitute a distinct type of thermostable α-galactosidases within glycoside hydrolase clan D but also represent the first members from the Archaea.

Biochemical Characterization of a Recombinant Xylanase from Thermus brockianus, Suitable for Biofuel Production

The first report of the heterologous production, purification and characterization of a xylanase from Thermus sp.

First Glycoside Hydrolase Family 2 Enzymes from Thermus antranikianii and Thermus brockianus with β-Glucosidase Activity

The first thermoactive GH family 2 enzymes with β-glucosidase activity have been identified and characterized and the hydrolysis of cellobiose is a unique property of TaGH2 when compared to other enzymes ofGH family 2.

Integrated molecular analysis of sugar metabolism of Sulfolobus solfataricus

This work reconstructed the central carbon metabolism in the hyperthermophilic crenarchaeon Sulfolobus solfataricus (glycolysis, gluconeogenesis and tricarboxylic acid cycle) on the basis of genomic, proteomic, transcriptomic and biochemical data.
