'''CHITINASE B FROM SERRATIA MARCESCENS'''<br />

==Overview==

==Chitinase B from Serratia Marcescens==
-
In this paper, we describe the structure of chitinase B from Serratia, marcescens, which consists of a catalytic domain with a TIM-barrel fold, and a 49-residue C-terminal chitin-binding domain. This chitinase is the, first structure of a bacterial exochitinase, and it represents one of only, a few examples of a glycosyl hydrolase structure having interacting, catalytic and substrate-binding domains. The chitin-binding domain has, exposed aromatic residues that contribute to a 55-A long continuous, aromatic stretch extending into the active site. Binding of chitin, oligomers is blocked beyond the -3 subsite, which explains why the enzyme, has chitotriosidase activity and degrades the chitin chain from the, nonreducing end. Comparison of the chitinase B structure with that of, chitinase A explains why these enzymes act synergistically in the, degradation of chitin.
