Proline is the only protein imino acid. In some proteins, proline is post-translationally hydroxylated to hydroxyproline. Such modifications occur to a large extent in hydroxyproline-rich glycoproteins (HPRG), which are involved in cell wall construction (Moore et al, 1991). Apart from the presence of proline in proteins, this amino acid also occurs in significant concentrations... 

There are no reports of the Hamaker constant (A) for CAJ in the literature, and its determination will be considered in our future works. Nevertheless, it is knovm that CAJ particles consist of molecular aggregates and cellular debris, which in turn is made up of hydroxyproline-rich glycoproteins (Beveridge, 1997). Rodin and Izmailova (Rodin and Izmailova, 1996) reported a value of A = 1 X 10 J (0.243 k T) for a hydroxyproline-rich...

Hydroxyproline-rich glycoproteins are among the most prominent proteins in cell walls. The hydroxylation of proline is one of over 100 post-translational modifications that can occur on amino acid residues in protein (137). As a result of protein turnover (31) and cell stress, sometimes these amino acids may be found in extracellular matrices. 

Plants contain at least three classes of hydroxyproline-rich glycoproteins 1) the cell wall proteins, 2) the arabinogalactan proteins, and 3) lectins. According to Cooper and Varner (23) the hydroxyproline-rich glycoprotein of the cell wall of carrots is secreted from the cytoplasm as a soluble monomer that slowly becomes insolubilized.
