Crystal Structure of the Lumenal Domain of Calnexin

Overview

The three-dimensional structure of the lumenal domain of the lectin-like, chaperone calnexin determined to 2.9 A resolution reveals an extended 140, A arm inserted into a beta sandwich structure characteristic of legume, lectins. The arm is composed of tandem repeats of two proline-rich, sequence motifs which interact with one another in a head-to-tail fashion., Identification of the ligand binding site establishes calnexin as a, monovalent lectin, providing insight into the mechanism by which the, calnexin family of chaperones interacts with monoglucosylated, glycoproteins.
