A Gymnosperm Extensin Contains the Serine-Tetrahydroxyproline Motif [PDF]
Plant Physiology, 1992 The extensin family is a diverse group of hydroxyproline-rich glycoproteins located in the cell wall and characterized by repetitive peptide motifs glycosylated to various degrees. The origin of this diversity and its relationship to function led us earlier to compare extensins of the two major groups of angiosperms from which we concluded that the ...

Purification and Partial Characterization of Tomato Extensin Peroxidase [PDF]
Plant Physiology, 1995 Early plant defense response is characterized by elevation of activity of peroxidases and enhanced insolubilization of hydroxyproline-rich glycoproteins, such as extensin, in the cell wall. The insolubilization process (cross-linking between soluble extensin precursor molecules) is catalyzed by extensin peroxidases.

Rhizobia Modulate Root-Hair-Specific Expression of Extensin Genes
Molecular Plant-Microbe Interactions, 1997 Three cDNAs (ext3, ext127, and ext26), originally isolated by differential screening from a root-hair cDNA library of Vigna unguiculata, were found to encode extensin-like cell wall proteins.

A Chenopod Extensin Lacks Repetitive Tetrahydroxyproline Blocks [PDF]
Plant Physiology, 1990 An extensin isolated from sugar beet (Beta vulgaris) cell suspension cultures fulfills all criteria for membership of the extensin family save one, notably, lack of the ;diagnostic' pentamer Ser-Hyp-Hyp-Hyp-Hyp. However, sequence analysis of the major tryptic peptides shows that sugar beet extensin shares a motif in common with tomato extensin P1 but ...

Recent advances on the post-translational modifications of EXTs and their roles in plant cell walls
Frontiers in Plant Science, 2012 The genetic set up and the enzymes that define the O-glycosylation sites and transfer the activated sugars to the cell wall protein backbone have remained unknown for a long time.

Atomic Force Microscopy (AFM) Analysis of Cell Wall Structural Glycoproteins in vitro
Bio-Protocol, 2015 Hydroxyproline-rich glycoproteins (HRGPs) are major protein components in dicot primary cell walls and generally account for more than 10% of the wall dry weight.

Investigating the Role of Extensin Proteins in Poplar Biomass Recalcitrance
BioResources, 2016 The biological conversion of cellulosic biomass to biofuel is hindered by cell wall recalcitrance, which can limit the ability of cellulases to access and break down cellulose. The purpose of this study was to investigate whether hydroxyproline-rich cell
