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 ...

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

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 ...

Mannan-binding lectin in malignancy

Molecular Immunology, 2013
Complement may play a dual role in cancer: it may contribute either to the development or to the inhibition of tumour growth. Its components may be candidate biomarkers facilitating the disease detection, its progress or effectiveness of therapy. Additionally, complement deficiencies may increase the risk of infections and contribute to the higher ...

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.

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.

Mannan-Binding Lectin and Mannan-Binding Lectin-Associated Serine Protease 2 in Acute Pancreatitis

Pancreas, 2011
Complement activation may play a prominent role in acute pancreatitis (AP). Mannan-binding lectin (MBL) and MBL-associated serine protease 2 (MASP-2) participate in complement activation. The objective of the present study was to evaluate the role of MBL and MASP-2 as markers in AP with regard to etiology, inflammatory activity, severity, and ...

Mannan binding lectin and viral hepatitis

Immunology Letters, 2007
Mannan binding lectin (MBL) is a pattern recognition molecule of the innate immune system that binds to sugars on the surface of invading micro-organisms. Target binding, complement activation and other functions of MBL are dependent on the presence of multiple carbohydrate recognition domains.

Synthesis of a Candida albicans tetrasaccharide spanning the β1,2-mannan phosphodiester α-mannan junction

Organic & Biomolecular Chemistry, 2012
The cell wall phosphomannan of Candida species is a complex N-linked glycoprotein with a glycan chain containing predominantly an α-linked mannose backbone with α-mannose branches. A minor β-mannan component is attached to the branches either via a glycosidic bond (acid stable β-mannan) or a phosphodiester bond (acid-labile β-mannan).
