The presence of chitin in so many organisms that can function as pathogens toward plants and higher animals makes it an attractive target for host recognition and enzymatic attack. Indeed, plants are well known to express chitinases in response to the presence of chitin-containing pathogens. More recently, chitinases and chitinase-like proteins have been identified in the genomes . . .
