WebAllergies to certain fruits such as banana, avocado, chestnut and kiwi are described in 30-70% of latex-allergic patients. This association is attributed to the cross-reactivity between the major latex allergen hevein and hevein-like domains (HLDs) from fruit class I chitinases. We aimed to assess t … WebApr 23, 2007 · Insects, molds and parasitic worms - all common sources of allergies or inflammation - produce billions of tons of chitin a year. Humans and other mammals lack chitin, but we do have specialized enzymes to break it down. The scientists wondered why. They discovered that chitin triggers an allergic inflammatory response in the lungs of …

Overview of Plant Chitinases Identified as Food Allergens
WebALLERGEN DESCRIPTION. Hev b 8 (13,56-58,60) is a profilin. Plant profilins are important panallergens. They are responsible for a significant percentage of pollen-related allergies. The observed frequencies of Hev b 8-specific IgE antibodies in sera of Latex-allergic patients in different risk groups range between 6 and 24% (1,57-58,60). WebMay 19, 2014 · Plant chitinases have been described as an important issue concerning food allergy because they can be either proteins overexpressed as PR-proteins or unexpectedly present in plant food as ... Chitinases production in the human body (known as "human chitinases") may be in response to allergies, and asthma has been linked to enhanced chitinase expression levels. Human chitinases may explain the link between some of the most common allergies (dust mites, mold spores—both of which … See more Chitinases (EC 3.2.1.14, chitodextrinase, 1,4-β-poly-N-acetylglucosaminidase, poly-β-glucosaminidase, β-1,4-poly-N-acetyl glucosamidinase, poly[1,4-(N-acetyl-β-D-glucosaminide)] glycanohydrolase, (1→4)-2-acetamido-2 … See more 1. Endochitinases (EC 3.2.1.14) randomly split chitin at internal sites of the chitin microfibril, forming soluble, low molecular mass multimer products. The multimer products includes di-acetylchitobiose, chitotriose, and chitotetraose, with the dimer being the … See more Regulation varies from species to species, and within an organism, chitinases with different physiological functions would be under different regulation mechanisms. For example, chitinases that are involved in maintenance, such as remodeling the cell wall, are … See more Chitinases have a wealth of applications, some of which have already been realized by industry. This includes bio-conversion of chitin to useful products such as fertilizer, the production of … See more Chitinivorous organisms include many bacteria (Aeromonads, Bacillus, Vibrio, among others), which may be pathogenic or detritivorous. They attack living arthropods, zooplankton or … See more Like cellulose, chitin is an abundant biopolymer that is relatively resistant to degradation. Many mammals can digest chitin and the specific chitinase levels in vertebrate species are adapted to their feeding behaviours. Certain fish are able to digest chitin. … See more Chitinases occur naturally in many common foods. Phaseoleus vulgaris, bananas, chestnuts, kiwifruit, avocados, papaya, and tomatoes, for example, all contain significant levels of chitinase, as defense against fungal and invertebrate attack.
