Chitotriosidase, a chitinase, and the 39‐kDa human cartilage glycoprotein, a chitin‐binding lectin, are homologues of family 18 glycosyl hydrolases secreted by human macrophages

Abstract
In various mammals, enzymatically active and inactive members of family 18 glycosyl hydrolases, containing chitinases, have been identified. In man, chitotriosidase is the functional chitinolytic enz...
