Chitin-binding, type 1, conserved site

InterPro entry
Short nameChitin-binding_1_CS

Description

A number of plant and fungal proteins that bind N-acetylglucosamine (e.g. solanaceous lectins of tomato and potato, plant endochitinases, the wound-induced proteins: hevein, win1 and win2, and the Kluyveromyces lactis killer toxin alpha subunit) contain this domain
[1]
. The domain may occur in one or more copies and is thought to be involved in recognition or binding of chitin subunits
[2, 3]
. In chitinases, as well as in the potato wound-induced proteins, the 43-residue domain directly follows the signal sequence and is therefore at the N terminus of the mature protein; in the killer toxin alpha subunit it is located in the central section of the protein.
