extensin metabolic process
The chemical reactions and pathways involving extensins, a group of 60-90 kDNA hydroxyproline (Hyp)-rich glycoproteins whose polypeptide backbone consists of many repeats of structural Ser(Hyp)4-6 motifs, with heavily glycosylated 1-4 arabinose residues O-linked to contiguous stretches of Hyp residues, with most of the Ser residues being O-galactosylated.
non-classical arabinogalactan protein metabolic process
The chemical reactions and pathways involving a cell wall arabinogalactan II glycoprotein where other amino acids besides Hyp, Ala, Ser, Thr and Gly can be present and grouped into regions, such as a Cys-rich or Asn-rich domains.
classical arabinogalactan protein metabolic process
The chemical reactions and pathways involving a cell wall arabinogalactan II glycoprotein, which is composed of a group of core protein containing Hyp, Ala, Ser, Thr and Gly as the major amino acid constituents, and the C-terminus is GPI anchored.
