Arabinogalactan protein is a type of protein found in plant cell walls. It is heavily glycosylated, with only 2-10% protein. It is acidic and contains hydroxyproline, serine, alanine and glycine amino acids predominantly. The carbohydrate chains contain galactose, arabinose, rhamnose, mannose, galacturonic acid and/or glucuronic acids and have a relatively high degree of polymerization, with a structure similar to arabinogalactan II. They are involved in cell-cell interactions and plant defence.
