چکیده
Jun a 1, the major allergen of pollen from the mountain cedar Juniperus ashei, has been crystallized using the hanging-drop vapor-diffusion method at 277 K. The crystals are monoclinic, space group P2(1), with unit-cell parameters a = 53.38, b = 113.48, c = 72.44 A, beta = 96.36 degrees and four molecules in the unit cell. A complete 2.5 A data set has been collected at 100 K with X-rays from a Cu Kalpha rotating-anode generator.

Crystal Structure of Jun a 1, the Major Cedar Pollen Allergen from Juniperus ashei, Reveals a Parallel -Helical Core*
Pollen from cedar and cypress trees is a major cause of seasonal hypersensitivity in humans in several regions of the Northern Hemisphere. We report the first crystal structure of a cedar allergen, Jun a 1, from the pollen of the mountain cedar Juniperus ashei (Cupressaceae). The core of the structure consists primarily of a parallel -helix, which is nearly identical to that found in the pectin...
متن کاملVariable expression of pathogenesis-related protein allergen in mountain cedar (Juniperus ashei) pollen.
Allergic diseases have been increasing in industrialized countries. The environment is thought to have both direct and indirect modulatory effects on disease pathogenesis, including alterating on the allergenicity of pollens. Certain plant proteins known as pathogenesis-related proteins appear to be up-regulated by certain environmental conditions, including pollutants, and some have emerged as...
متن کاملMolecular analysis confirms the long-distance transport of Juniperus ashei pollen
Although considered rare, airborne pollen can be deposited far from its place of origin under a confluence of favorable conditions. Temporally anomalous records of Cupressacean pollen collected from January air samples in London, Ontario, Canada have been cited as a new case of long-distance transport. Data on pollination season implicated Juniperus ashei (mountain cedar), with populations in c...
متن کاملPlant-expressed recombinant mountain cedar allergen Jun a 1 is allergenic and has limited pectate lyase activity.
BACKGROUND Mountain cedar (Juniperus ashei) pollen commonly causes a winter time allergic rhinitis in the central USA. Jun a 1 is the dominant allergenic protein, but biologically active recombinant Jun a 1 has not been successfully expressed, despite numerous attempts with several expression systems. METHOD Jun a 1 cDNA was inserted into a tobacco mosaic virus vector and transferred to Agrob...
متن کاملPredicting and Quantifying Pollen Production in Juniperus Ashei Forests
Juniperus ashei pollen has been reported as a major airborne allergen in regions of Texas and Oklahoma. Pollen production across these populations was examined in order to support a pollen forecast system. Four locations in Texas and 2 locations in Oklahoma were chosen as study sites. Trees in each location were measured, cone production was evaluated based on a rating system, and percent tree ...
