', Journal of Biological Chemistry, vol. 295, no. 52, pp. 18539-18552 . https://doi.org/10.1074/jbc.RA120.016149
Arabinogalactan proteins (AGPs) are plant proteoglycans with functions in growth and development. However, these functions are largely unexplored, mainly because of the complexity of the sugar moieties. These carbohydrate sequences are generally anal
