physiological function
physiological function
-
the beta-xylosidase exhibits synergism with endoxylanase upon hydrolysis of glucuronoxylan as well as with alpha-L-arabinofuranosidase and endoxylanase upon hydrolysis of arabinoxylan. Addition of beta-xylosidases increases efficiency of hydrolysis of plant raw materials with high hemicellulose content such as maize cobs by the enzymic preparation Celloviridine G20x depleted of its own beta-xylosidase
physiological function
-

Addition of beta-xylosidases increases efficiency of hydrolysis of plant raw materials with high hemicellulose content such as maize cobs by the enzymic preparation Celloviridine G20x depleted of its own beta-xylosidase
physiological function
when incubated in combination with bifunctional xylanase-ferulic acid esterase Xyn10D-Fae1A, Xyl3A improves the release of xylose monomers from a hemicellulosic xylan substrate, suggesting that these two enzymes function synergistically to depolymerize xylan
physiological function
in T-DNA insertion mutant, mucilage release is both patchy and slow and seeds display delayed germination. Developmental analysis of mutant seeds reveals no change in mucilage secretory cell morphology, but changes in monosaccharide quantities are detected. Chemical and immunological analyses of mucilage extracted from bxl1 mutant seeds and antibody staining of developing seed coats reveal an increase in (1-5)-linked arabinans, suggesting that BXL1 is acting as an a-L-arabinofuranosidase in the seed coat
physiological function
RuBG3A or RuBG3B alone do not release any reducing sugars from xylan. The addition of each enzyme into the reaction mixture of xylanase XynR8 improves the liberation of reducing sugars. The addition of RuBG3A with an activity ratio of 10:1 (xylosidase/xylanase) increases the liberation to 218% of that in the presence of XynR8 alone; RuBG3A or RuBG3B alone do not release any reducing sugars from xylan. The addition of each enzyme into the reaction mixture of xylanase XynR8 improves the liberation of reducing sugars. The addition of RuBG3B with an activity ratio of 5:1 (xylosidase/xylanase) increases the liberation to 169% of that in the presence of XynR8 alone. RuBG3B shows no synergism with xylanase XynR8 at the optimal pH 7.5, but at pH 5.5, indicating that RuBG3B may have different pH preferences between aryl xylosidic substrate 4-nitrophenyl-beta-D-xylopyranoside and xylooligisaccharide xylan
physiological function

physiological function

strain grows well on locust bean galactomannan, Solka floc, wheat bran and pectin and at 45°C
physiological function
-
screening of thermophilic and thermotolerant filamentous fungi for the production of beta-xylosidase and arabinanase at different temperatures. beta-Xylosidase and arabinanase activities from mycelial extract (intracellular form) are higher in cultures grown at high temperatures (35-40°C), while the correspondent extracellular activities are favorably secreted from cultures at 30°C. Aspergillus niger and Aspergillus thermomutatus are the filamentous fungi with the most expressive production of beta-xylosidase and arabinanase, respectively
physiological function
-
growth on corncobs (coarse) induces the highest titres of xylosidase and acetyl esterase

RuBG3A or RuBG3B alone do not release any reducing sugars from xylan. The addition of each enzyme into the reaction mixture of xylanase XynR8 improves the liberation of reducing sugars. The addition of RuBG3A with an activity ratio of 10:1 (xylosidase/xylanase) increases the liberation to 218% of that in the presence of XynR8 alone

RuBG3A or RuBG3B alone do not release any reducing sugars from xylan. The addition of each enzyme into the reaction mixture of xylanase XynR8 improves the liberation of reducing sugars. The addition of RuBG3B with an activity ratio of 5:1 (xylosidase/xylanase) increases the liberation to 169% of that in the presence of XynR8 alone. RuBG3B shows no synergism with xylanase XynR8 at the optimal pH 7.5, but at pH 5.5, indicating that RuBG3B may have different pH preferences between aryl xylosidic substrate 4-nitrophenyl-beta-D-xylopyranoside and xylooligisaccharide xylan
