Antioxidant and antimutagenic activity of mannan neoglycoconjugates: Mannan–human serum albumine and mannan–penicillin G acylase

Mutation Research/Genetic Toxicology and Environmental Mutagenesis, 2006
The antioxidant and antimutagenic activity of the yeast cell-wall mannan and mannan conjugates--in particular the mannan of Saccharomyces cerevisiae (M-S.c.) and conjugates of mannan S. cerevisiae with human serum albumin (M-HSA1, M-HSA2) and the microbial enzyme penicillin G acylase (M-PGA)--were evaluated in vitro in the unicellular flagellate ...

Immunostimulatory properties of coffee mannans

Molecular Nutrition & Food Research, 2009
AbstractCoffee infusion mannans are acetylated polysaccharides containing single Galp and Araf residues as side chains of a β‐(1 → 4)‐Manp backbone. These mannans are structurally similar to the bioactive acetylated mannans from Aloe vera (AV). In this study, acetylated mannans were obtained from two coffee infusions prepared from light and dark ...

Mannosylphosphate transfer to yeast mannan

Biochimica et Biophysica Acta (BBA) - General Subjects, 1999
Mannoproteins located in the outermost layer of yeast cell wall determine the wall's porosity and thereby regulate leakage of proteins from the periplasmic space and entrance of macromolecules from the environment. In several yeasts, including Saccharomyces cerevisiae, the glycan portion of mannoproteins is composed not only of neutral oligosaccharides

An approach to the sequencing of yeast mannan

Biochemical and Biophysical Research Communications, 1975
Summary A “nearest neighbor” analysis of the products of partial acetolysis of yeast mannan was carried out in an attempt to learn whether the side chains in the polysaccharide are ordered in a sequence or occur randomly. The results suggest that the arrangement is nonrandom, but they do not give unequivocal support to a single repeating sequence.

The enzymic synthesis of yeast mannan

Biochemical and Biophysical Research Communications, 1963
Abstract When guanosine diphosphate mannose (GDP-mannose) was first isolated from yeast, it was proposed that this compound might be the precursor of mannan ( Cabib and Leloir, 1954 ). Evidence supporting this hypothesis will be outlined in the present communication.

A MANNAN PRODUCED BY BACILLUS POLYMYXA

Canadian Journal of Chemistry, 1959
During the fermentation of glucose, sucrose, or lactose by Bacilluspolymyxa, a mixture of polysaccharides is formed, one of which has been isolated by mild procedures and shown to contain mannose as the only sugar together with approximately 13% protein. Acid hydrolysis of the methylated mannan gave 2,3,4,6-tetra-O-methyl-D-mannose, 2,4,6-tri-O-methyl-

Introduction to mannan-binding lectin

Biochemical Society Transactions, 2003
Mannan-binding lectin (MBL) was first discovered as a plasma opsonin for baker's yeast and was independently characterized biochemically. It belongs to the small subfamily of collectins: C-type lectins possessing a collagen-like domain. MBL is synthesized by the liver and secreted into the bloodstream.

A procoagulant chemically sulfated mannan

Carbohydrate Polymers, 2016
Disorders of hemostasis can produce innumerous problems. Polysaccharides have been studied both as anticoagulant and as procoagulant agents. A mannan with a main chain of α-(1 → 6)-linked-Manp units, branched at O-2 mainly by side-chains of 2-O-linked-α-Manp units was chemically sulfated, structurally characterized by NMR and GC-MS (methylation ...

Quantification of mannan-binding lectin

Journal of Immunological Methods, 2006
Mannan-binding lectin (MBL) is attracting considerable interest due to its role in the immune defense. The high frequency of congenital MBL deficiency makes it feasible to evaluate clinical relevance through epidemiological investigations on fairly limited numbers of patients.
