Immobilized ?-glucanases and their applications

Biotechnology Letters, 1979
A number of β-glucanase active enzyme preparations were successfully immobilized either by adsorption on Duolite S-761 phenol-formaldehyde resin or covalently on silanized Spherosil XOB-075 porous silica beads to obtain remarkably stable active biocatalysts.

Proteinaceous inhibitors of endo-β-glucanases

Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2004
Both plants and filamentous phytopathogens secrete proteins that inhibit endo-beta-glucanases. The first endo-beta-glucanase inhibitor proteins to be discovered are XEGIP, a tomato protein that inhibits fungal xyloglucan-specific endo-beta-1,4-glucanases, and GIP1, an oomycete protein that inhibits endo-beta-1,3-glucanases produced by the plant host ...

Glucanase activity in coleoptiles of Avena

Archives of Biochemistry and Biophysics, 1969
Abstract The presence of five different β-glucanases has been investigated in coleoptiles of Avena with the use of specific substrates. A high activity of β-1,3-glucanase is found associated with the coleoptiles. With regard to β-1,4-glucanase activity a strong activity of exo -cellulase which splits glucose (or cellobiose) from the end of the ...

β-D-1,6-Glucanase in Streptomyces

Nature, 1963
ACCORDING to Reese et al.1, β-D-1,6-glucan rarely occurs in Nature, yet many fungi are able to produce an enzyme capable of hydrolysing it. Production of β-D-1,6-glucanase by Streptomyces has not been reported.

Structure of the beta- 1,3-1,4-glucanase gene ofBacillus macerans: Homologies to other beta-glucanases

Molecular and General Genetics MGG, 1990
The nucleotide sequence of an 852 base pair (bp) DNA fragment containing the entire gene coding for thermostable beta-1,3-1,4-glucanase of Bacillus macerans has been determined. The bglM gene comprises an open reading frame (ORF) of 711 bp (237 codons) starting with ATG at position 93 and extending to the translational stop codon TAA at position 804 ...

Measurement of endo-1,4-β-Glucanase

2012
Several procedures are available for the measurement of endo-1,4-β-glucanase (EG). Primary methods employ defined oligosaccharides or highly purified polysaccharides and measure the rate of hydrolysis of glycosidic bonds using a reducing-sugar method. However, these primary methods are not suitable for the measurement of EG in crude fermentation broths

β-Glucanase of yeast

Biochemical and Biophysical Research Communications, 1965
Abstract The basal cell wall structure of yeasts which is responsible for the shape and rigidity of the yeast cell is a β-glucan, containing both β 1,3 and β 1,6 linkages (Phaff, 1963) . During conjugation, two yeast cells of opposite mating type fuse by dissolution of cell wall material between them, leading to a typical dumbbell-shaped zygote ...

Fungal cell wall chitinases and glucanases

Microbiology, 2004
The fungal cell wall is a complex structure composed of chitin, glucans and other polymers, and there is evidence of extensive cross-linking between these components. The wall structure is highly dynamic, changing constantly during cell division, growth and morphogenesis.

Natural effectors of β-1,3-glucanases activator of the β-1,3-glucanases of marine mollusks

Chemistry of Natural Compounds, 1992
The capacity of certain extracts of marine invertebrates of the Indian and Pacific Oceans for activating β-1,3-glucanases has been detected. It has been shown that an individual compound — swinholide A from the spongeTheonella swinhoei — specifically activates β-1,3-glucanases of bivlve mollusks.

An assay for glucanase activity in wine

Enzyme and Microbial Technology, 2004
Abstract A method to measure specific β(1,3)-glucanase activity in wines has been developed, and is based on the measurement of the kinetics of glucose release in the presence of laminarin (a β(1,3)-glucan from Laminaria digitata). The reaction time and substrate amount have been optimised to allow for measurements in wine conditions.
