Little information exists concerning the biochemical route of mannitol catabolism in higher plant cells. In this study, the role of a recently discovered mannitol 1-oxidoreductase (MDH) in mannitol catabolism was investigated. Suspension cultures of celery (Apium graveolens L. var dulce [Mill.]

BACKGROUND This study was performed to get further insights into antibody responses to cross-reactive carbohydrate determinants (CCD), including initial experiments to prove the biological activity of anti-CCD IgE. Earlier studies have shown that IgE specific for CCD occurs in about 25% of

Prisijungti Registracija

In the polyol producing plant, celery (Apium graveolens L.), mannitol is a major photosynthetic product and a form in which carbohydrate is translocated. Measurements of whole leaf extracts of celery indicated substantial activity of the following enzymes: mannose-6-P reductase, mannose-6-P

Mimotopes for Api g 5, a Relevant Cross-reactive Allergen, in the Celery-Mugwort-Birch-Spice Syndrome.

OBJECTIVE In the celery-mugwort-birch-spice syndrome, a significant proportion of IgE is directed against high molecular weight (HMW) glycoproteins, including the celery allergen Api g 5. BIP3, a monoclonal antibody originally raised against birch pollen, recognizes HMW allergens in birch and

Celery allergens in patients with positive double-blind placebo-controlled food challenge.

BACKGROUND Recently, for the first time, allergy to celery was confirmed by double-blind placebo-controlled food challenge (DBPCFC). Api g 1, Api g 4, cross-reactive carbohydrate determinants (CCD), and a 60 kDa allergen have been described as celery allergens. OBJECTIVE To get insights in IgE

Biosynthesis of Sucrose and Mannitol as a Function of Leaf Age in Celery (Apium graveolens L.).

Prisijungti Registracija

In celery (Apium graveolens L.), the two major translocated carbohydrates are sucrose and the acyclic polyol mannitol. Their metabolism, however, is different and their specific functions are uncertain. To compare their roles in carbon partitioning and sink-source transitions, developmental changes

Mannose-6-Phosphate Reductase, a Key Enzyme in Photoassimilate Partitioning, Is Abundant and Located in the Cytosol of Photosynthetically Active Cells of Celery (Apium graveolens L.) Source Leaves.

Mannitol, a major photosynthetic product and transport carbohydrate in many plants, accounts for approximately 50% of the carbon fixed by celery (Apium graveolens L.) leaves. Previous subfractionation studies of celery leaves indicated that the enzymes for mannitol synthesis were located in the

Definition of immunogenic carbohydrate epitopes.

Prisijungti Registracija

Carbohydrates are known as sources of immunological cross-reactivity of allergenic significance. In celery and in cypress pollen, the major allergens Api g 5 and Cup a 1 are recognised by antisera raised against anti-horseradish peroxidase and by patients' IgE which apparently bind carbohydrate

Allergens in celery and zucchini.

The aim of this study was to confirm allergy to celery tuber and to zucchini, for the first time, by DBPCFC, and to identify the allergens recognized by IgE from DBPCFC-positive patients. Therefore, raw vegetables were hidden in a broccoli drink, and a DBPCFC-procedure was developed that consisted

OBJECTIVE The purpose of this study was to characterize the IgE binding components of celery root by immunoblot analysis and to investigate the cross-reactive nature of the allergens. BACKGROUND Sensitization to celery is very common in patients hypersensitive to mugwort pollen and birch pollen, and

Allergic sensitization to native and heated celery root in pollen-sensitive patients investigated by skin test and IgE binding.

Prisijungti Registracija

The rates of sensitization and allergy to four birch pollen related plant foods were investigated in a group of 167 patients who were sensitive to at least one kind of pollen and one particular food. Sensitivity was concluded from a positive skin prick test or the determination of specific IgE,

Both mannitol and sucrose (Suc) are primary photosynthetic products in celery (Apium graveolens L.). In other biological systems mannitol has been shown to serve as a compatible solute or osmoprotectant involved in stress tolerance. Although mannitol, like Suc, is translocated and serves as a

[(14) C]-Assimilate translocation in the light and dark in celery (Apium graveokns) leaves of different ages.

The 2 major photosynthetic products and translocated carbohydrates in celery (Apium graveolens L.) are sucrose and the sugar alcohol, mannitol. Sucrose is produced and utilized in leaves of all ages. Mannitol, however, is synthesized primarily in mature leaves, utilized in young leaves and stored in

The effect of abiotic stresses on carbohydrate status of olive shoots (Olea europaea L.) under in vitro conditions.

Olive plants produce both sucrose and mannitol as major photosynthetic products. Contrary to previously studied celery [Vítová et al., Mannitol utilisation by celery (Apium graveolens) plants grown under different conditions in vitro. Plant Sci 2002; 163: 907-16], in vitro these carbohydrates were

Understanding the biological rationale for the diversity of cellulose-directed carbohydrate-binding modules in prokaryotic enzymes.

Plant cell walls are degraded by glycoside hydrolases that often contain noncatalytic carbohydrate-binding modules (CBMs), which potentiate degradation. There are currently 11 sequence-based cellulose-directed CBM families; however, the biological significance of the structural diversity displayed
