Tremella fuciformis

The molecular weight (94,000) was smaller than that of other microbial P-mannosidases such as Aspergillus o/jCTe( 120,000-135,000) and Tremella fuciformis (160,000-200,000). The final product from the oligosaccharides with the enzyme was mainly D-mannose and the enzymatic activity was not inhibited by D-mannose or mannose-derivatives such as D-mannosamine, D-mannonic acid and D-mannitol. 

AIDS therapeutic effects. Water extract of the dried rhizome taken orally by adults was active. A pharmaceutical solution containing fruit bodies of Tremella fuciformis, Daucus carota rhizome. Astragalus mongho licus root, and Zizyphus jujuba fruits, honey, vitamin A palmitate, zinc sulfate, and vitamin C was useful for controlling acquired immunodifficiency syndrome (AIDS), cancer, and infections . 

Polysaccharides CS-F30, from cultural mycelia of Cordyceps sinensis decreased plasma cholesterol in mice (Jones et al., 1998). The glucuronox-ylomannan from Tremella fuciformis fruiting bodies brought about reduction in the plasma cholesterol level in mice (Wang and Ng, 1999).

Several acidic oligosaccharides, isolated from the acidic heteroglycan of the edible mushroom Tremella fuciformis, have been characterized by methylation analysis and n.m.r. spectroscopy and the structure (31) has been proposed for the parent polysaccharide.A similar structure has been proposed for a cell-wall polysaccharide isolated from growing cultures of haploid cells of two strains of T. fuciformis-, two extracellular polysaccharides showed only minor variations from this structure. ... 

D-2-Acetamido-2-deoxyhexosidase has been purified from an edible mushroom, Tremella fuciformis, to a single protein band (mol. wt. 1.25 x 10 by gel filtration) on disc gel electrophoresis. The enzyme (pH optimum 5.0, 0,19... 

A water-soluble acidic polysaccharide is present in the outer layer of the cell walls of Tremella fuciformis which contains residues of D-glucuronic acid, D-mannose, and D-xylose (0.5 3.8 1.0). Structural studies have shown that this polysaccharide has a (1 3)-linked D-mannan backbone to which are attached single residues of D-glucuronic acid, D-mannose, and D-xylose at 0-2. 

The structures of a water-soluble D-glucan (20) and an alkali-soluble d-glucan (21) from the fruit body of Auricularia auricula-judae have been established. The structural resemblance of polysaccharides from Tremella fuciformis to those of other Tremella species and the group Cryptococcus is...
