Extensins: Self-Assembly, Crosslinking, and the Role of Peroxidases [PDF]
Frontiers in Plant Science, 2021 The extensin (EXT) network is elaborated by the covalent intermolecular crosslinking of EXT glycoprotein monomers, and its proper assembly is important for numerous aspects of basic wall architecture and cellular defense.
