Lots of insects, fungus and bacteria contain chitin cells, so a plant will produce chitinase …
WebIn mammals, despite the absence of endogenous chitin, a number of chitinases and chitinase-like proteins (C/CLPs) have been identified. However, their roles have only recently begun to be elucidated. Acidic mammalian chitinase (AMCase) inhibits chitin-induced innate inflammation; augments chitin-free, allergen-induced Th2 inflammation; … WebHowever, chitinase of S. indica still needs to be characterized. We functionally characterized a chitinase (SiChi) in S. indica. The result showed that the purified SiChi protein confers high chitinase activity; importantly, SiChi inhibits the conidial germination of Magnaporthe oryzae and Fusarium moniliforme. After the successful colonization ...
