STRUCTURE OF HUMAN CHITOTRIOSIDASE

Overview

Chitin hydrolases have been identified in a variety of organisms ranging, from bacteria to eukaryotes. They have been proposed to be possible, targets for the design of novel chemotherapeutics against human pathogens, such as fungi and protozoan parasites as mammals were not thought to, possess chitin-processing enzymes. Recently, a human chitotriosidase was, described as a marker for Gaucher disease with plasma levels of the enzyme, elevated up to 2 orders of magnitude. The chitotriosidase was shown to be, active against colloidal chitin and is inhibited by the family 18, chitinase inhibitor allosamidin. Here, the crystal structure of the human, chitotriosidase and complexes with a chitooligosaccharide and allosamidin, are described. The structures reveal an elongated active site cleft, ...
