For the purification of RHG, which has been described before (6), A. aculeatus was grown in sugar-beet pulp medium for 48 h. From a 2 1 culture containing 3.2 g protein, about 5 mg RHG was obtained after purification. Analysis by SDS-PAGE revealed only one band of about 55 kDa and thus the enzyme appeared to be pure. After N-glycanase treatment and SDS-PAGE analysis, a smaller protein band of about 46 kDa was visible (Fig.l). [Pg.908]

Nishimura and Yamada [10-11] introduced a water-soluble polymeric support having a linker recognized by ceramide glycanase for a synthesis of ganghoside GM3 (17). Synthesis of the polymerizable lactose derivative (14) with a ceramide glycanase sensitive linker is shown in Scheme 10.3. The lactosyl ceramide (Lac-Ger) mimetic glycopolymer (15) is obtained from the monomeric precursor (14) by co-polymerization with acrylamide. [Pg.449]

T. reesei culture filtrate by gel chromatography (10), contained both the 20 kDa xylanase, another glycanase with high laminarinase and low xylanase activity, and a hitherto unidentified esterase. When supplemented with / -xylosidase, the xylanases and esterase of this preparation released about half of the xylose and acetic acid of the substrate (Table IV). When purified acetyl esterase was added, the yields of xylose and acetic acid increased further about 1.6-fold. [Pg.636]

Up to the beginning of the 1990 s most of the work on thiooligosaccharides was devoted to their synthesis. During the last few years, tailor-made complex or sophisticated thiooligosaccharides were obtained and used both in biochemical and X-ray studies for getting a better understanding of the mechanism of action of glycanases. [Pg.114]

Although most of the glycosides 6-12 showed some inhibition towards the j3-glycanases available to us (18], it was the epoxybutyl -cellobioside 7 (n = 2) that was an efficient inhibitor of one particular enzyme. Also, in view of the chiral nature of an enzyme, it seemed an especially good idea to prepare molecules such as 7 in optically-pure form. We therefore began a program to synthesize the pure diastereoisomers 6a,6b,7a and7b. [Pg.193]

Cellulose, the most abundant of all biopolymers, is extremely stable but is attacked by a host of bacterial and fungal (3-glycanases.96 Animals do not ordinarily produce cellulases but some termites do.97 Cellulase structures are varied, being represented by 10 of 57 different glycosylhydrolase families.98 Most, like lysozyme, retain the P configuration in their products but some invert.98 100... [Pg.602]

Plants synthesize l,3-(3-glucanases that hydrolyze the glycans of fungal cell walls. Synthesis is induced by wounding as a defense reaction (see Box 20-E). These glycanases also function in the removal of callose.146... [Pg.1148]
