Genes for the Extensins, an Abundant Class of Proteins

  • J. E. Varner
Part of the Basic Life Sciences book series (BLSC, volume 41)


Hydroxyproline occurs in only a few classes of proteins; however, it is one of the most abundant amino acids. Most of these proteins are located in extracellular matrices, for example, the collagens of animals and the arabinogalactan proteins and extensins (hydroxyproline-rich glycoproteins or HRGPs) of plants. It is because of this that hydroxyproline is a major constituent of extracellular matrix proteins in both plants and animals.
