Heterologous expression and characterization of a glucose-stimulated β-glucosidase from the termite Neotermes koshunensis in Aspergillus oryzae [PDF]

open access: yesApplied Microbiology and Biotechnology, 2010
Neotermes koshunensis is a lower termite that secretes endogenous β-glucosidase in the salivary glands. This β-glucosidase (G1NkBG) was successfully expressed in Aspergillus oryzae. G1NkBG was purified to homogeneity from the culture supernatant through ammonium sulfate precipitation and anion exchange, hydrophobic, and gel filtration chromatographies ...

Characteristics of dispersal flight and disperser production in an Asian dry-wood termite, Neotermes koshunensis (Isoptera, Kalotermitidae) [PDF]

open access: yesInsectes Sociaux, 2018
Differences in the dispersal flight patterns among termite families are correlated with the difference between the two life history characteristics exhibited by this group: “separate-piece nesters” versus “single-piece nesters.” However, information remains limited on the phenology and the life history characteristics of single-piece nesters, impeding ...

Poikilolaimus carsiops n. sp. (Rhabditida: Rhabditidae) associated with Neotermes koshunensis (Kalotermitidae) in Kenting National Park, Taiwan [PDF]

open access: yesNematology, 2011
Abstract During a survey of termite-associated nematodes in southern Taiwan (Kenting National Park), two species of Poikilolaimus, Poikilolaimus cf. floridensis and an undescribed species, were isolated from termites in the family Kalotermitidae.

Alate differentiation and compound-eye development in the dry-wood termite Neotermes koshunensis (Isoptera, Kalotermitidae)

Insectes Sociaux, 2006
In social insects, caste-specific characters develop in the postembryonic differentiation processes. However, the mechanisms of caste-specific organ development have yet to be elucidated. In order to obtain insights into the relationship between caste differentiation and the regulation of organ development, we determined the caste-developmental pathway

Damage and ecological characteristics of termite Neotermes koshunensis on Taiwan cherry tree Cerasus campanulata in Okinawa Island

Journal of Asia-Pacific Entomology, 2018
Abstract Termites are typical house pests that can also be harmful pests for living trees, although this topic has not received much attention. To clarify the damage to trees caused by dry-wood termites (Neotermes koshunensis), and the ecological characteristics of such damage, we conducted a study on Taiwan cherry trees (Cerasus campanulata) grown ...

A digestive β-glucosidase from the salivary glands of the termite, Neotermes koshunensis (Shiraki): distribution, characterization and isolation of its precursor cDNA by 5′- and 3′-RACE amplifications with degenerate primers

Insect Biochemistry and Molecular Biology, 2002
beta-Glucosidase activity [EC 3.2.1.21] was measured in the salivary glands and the gut of wood-eating termite, Neotermes koshunensis (Shiraki). 75% of the activity was detected in the salivary glands, whereas 15% of the activity was present in the hindgut, where numerous symbiotic flagellates reside.

High-resolution structures ofNeotermes koshunensisβ-glucosidase mutants provide insights into the catalytic mechanism and the synthesis of glucoconjugates

Acta Crystallographica Section D Biological Crystallography, 2012
NkBgl, a β-glucosidase from Neotermes koshunensis, is a β-retaining glycosyl hydrolase family 1 enzyme that cleaves β-glucosidic linkages in disaccharide or glucose-substituted molecules. β-Glucosidases have been widely used in several applications. For example, mutagenesis of the attacking nucleophile in β-glucosidase has been conducted to convert it ...
