Asthma is a complex and heterogeneous syndrome in which the airway mucosa is abnormal and inflamed. Although its causes are unknown, there are strong clues: it runs in families, and many, but by no means all, patients with asthma have signs and symptoms of IgE responses to common allergens.

Chitinases are found in many organisms, and their properties seem to be closely related to their biological function. In this chapter, the physicochemical properties of chitinases such as molecular size are compared among organisms, and the optimum and stability conditions for chitinase activity are described.

Multiple chitinases of an endophytic Serratia proteamaculans 568 generate chitin oligomers
Bioresource Technology, 2012 Serratia proteamaculans 568 genome revealed the presence of four family 18 chitinases (Sp ChiA, Sp ChiB, Sp ChiC, and Sp ChiD). Heterologous expression and characterization of Sp ChiA, Sp ChiB, and Sp ChiC showed that these enzymes were optimally active ...

In this review we describe inhibition of chitinases from bacteria, fungi, plants and animals by allosamidin and its derivatives, cyclic peptides, styloguanidin and divalent cations. Most information is available for allosamidin, whose important structural features necessary for inhibition are known. At least one N-acetylallosamine sugar must be present,

Chitinases—Potential Candidates for Enhanced Plant Resistance towards Fungal Pathogens
Agriculture (Switzerland), 2018 Crop cultivation is crucial for the existence of human beings, as it fulfills our nutritional requirements. Crops and other plants are always at a high risk of being attacked by phytopathogens, especially pathogenic fungi.

Chitinases in biological control
1999The public concern over the harmful effects of chemical pesticides on the environment and human health has enhanced the search for safer, environmentally friendly control alternatives. Control of plant pests by the application of biological agents holds great promise as an alternative to the use of chemicals.

Chitinase inhibitor allosamidin promotes chitinase production of Streptomyces generally
International Journal of Biological Macromolecules, 2008Allosamidin is a family 18 chitinase inhibitor produced by Streptomyces. In its producing strain, Streptomyces sp. AJ9463, allosamidin promotes production of the family 18 chitinase originated from chi65 in a chitin medium through the two-component regulatory system encoded by chi65R and chi65S, which were present at the 5'-upstream region of chi65.

Chitinases and chitinase-like proteins in TH2 inflammation and asthma
Journal of Allergy and Clinical Immunology, 2005Chitin is the second most abundant biopolymer in nature, where it protects crustaceans, parasites, fungi, and other pathogens from the adverse effects of their environments, hosts, or both. Because chitin does not exist in mammals, it had been assumed that the chitinases that degrade it are also restricted to lower life forms.

Chitin is the second most abundant organic and renewable source in nature, after cellulose. Chitinases are chitin-degrading enzymes. Chitinases have important biophysiological functions and immense potential applications. In recent years, researches on fungal chitinases have made fast progress, especially in molecular levels.

The structure and action of chitinases
1999Chitin is second only to cellulose in biomass and it is an important component of many cell wall structures. Several families of enzymes, of distinctly different structure, have evolved to hydrolyze this important polysaccaride. Glycohydrolase family 18 enzymes, chitinases, are characterized by an eight-fold alpha/beta barrel structure; it has ...
