TL;DR: Chitin and chitosan enhanced the release of the platelet derived growth factor-AB (PDGF-AB) and the transforming growth factor -β1(TGF-β1) from the platelets, particularly, more with chitOSan.

TL;DR: 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, is described, which represents one of only a few examples of a glycosyl hydrolase structure having interacting catalytic and substrate-binding domains.
Abstract: 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.
