Domain

Chitin binding domain (IPR002557)

Short name: Chitin-bd_dom

Domain relationships

None.

Description

This entry represents a chitin binding domain [PMID: 10770921]. It is found in (amongst others) the Peritrophin-A chitin binding proteins, particularly the peritrophic matrix proteins of insects and animal chitinases [PMID: 9651363, PMID: 8621536, PMID: 9256413]. Copies of the domain are also found in some baculoviruses. It is an extracellular domain that contains six conserved cysteines that probably form three disulphide bridges. Chitin binding has been demonstrated for a protein containing only two of these domains [PMID: 9651363].
