Extensin--a major cell wall glycoprotein.

Plant, Cell and Environment, 1986
Abstract The structure of extensin is described in detail. It has a hydroxyproline‐rich backbone, which contains repeating peptides glycosylated by short side chains and it adopts a polyproline II helical conformation. The glycoprotein is synthesized intracellularly and soluble precursors are secreted to the wall, where they are bound, perhaps, by the ...

An intramolecular linkage involving isodityrosine in extensin

Phytochemistry, 1984
We isolated isodityrosine, a diphenyl ether linked amino acid, from cell wall hydrolysates and from two tryptic peptides of extensin. Determination of the molecular weights, net charges and composition of the peptides indicated that isodityrosine (IDT) can form a short intramolecular linkage in sequences consisting of:

Genome-Wide Analysis of Proline-Rich Extensin-Like Receptor Kinases (PERKs) Gene Family Reveals Their Roles in Plant Development and Stress Conditions in Oryza sativa L.

Plant Science, 2023
Proline-rich extensin-like receptor kinases (PERKs) play a crucial role in a wide range of biological processes in plants. In model plants like Arabidopsis, the PERK gene family has been well investigated. Conversely, no information available on the PERK

Exploring the extensin gene family: an updated genome-wide survey in plant and algae.

Journal of Experimental Botany, 2023
Extensins (EXTs), a class of hydroxyproline-rich glycoprotein with multiple Ser-Pro3-5 motifs, are known to play roles in cell wall reinforcement and environmental responses.

The extensin protein SAE1 plays a role in leaf senescence and is targeted by the ubiquitin ligase SlSINA4 in tomato.

Journal of Experimental Botany, 2023
Extensins are hydroxyproline-rich glycoproteins (HRGPs) and generally play a structural role in cell wall integrity. In this study, we determined a novel role of tomato (Solanum lycopersicum) senescence-associated extensin1 (SAE1) in leaf senescence ...

Extensin and Arabinogalactan-Protein Biosynthesis: Glycosyltransferases, Research Challenges, and Biosensors

Frontiers in Plant Science, 2016
Recent research, mostly in Arabidopsis thaliana, has led to the identification and characterization of the glycosyltransferases responsible for the biosynthesis of two of the most functionally important and abundant families of plant cell wall proteins ...

Tomato extensin and extensin-like cDNAs: structure and expression in response to wounding

Plant Molecular Biology, 1991
Two tomato cDNA libraries were synthesized from poly(A)+ RNAs isolated from unwounded and wounded tomato stems. These cDNA libraries were packaged in lambda gt10 and screened by in situ plaque hybridization with a tomato extensin gene clone (pTom 5.10). Several cDNA clones were identified and isolated from both libraries in this manner and subjected to

Structure and regulation of tobacco extensin

The Plant Journal, 1993
A tobacco cDNA clone (pCNT1) was characterized that encodes an extensin apoprotein almost entirely composed of the repeats Ser—Pro4(—Lys2), Pro—Tyr2—Pro2—His and Thr—Pro—Val—Tyr—Lys. In healthy plants extensin transcripts are abundant in the roots, less prevalent in the stem and rare in the leaves.

Molecular characterization of maize extensin expression

Plant Molecular Biology, 1993
This study concerned the developmental regulation of wall-localized, hydroxyproline-containing proteins in maize tissues and organs. Silk and pericarp cell walls contained more peptidyl hydroxyproline than did walls of any vegetative tissue, although all tissues and organs accumulated these proteins as they matured. In many tissues, hydroxyproline-rich

Assessing the Self-Assembly of Native P1 Extensin Glycoproteins on Highly Oriented Pyrolytic Graphite (HOPG) Using Atomic Force Microscopy (AFM).

Langmuir
Extensins (EXTs) are structural glycoproteins found in plant cell walls that contribute to the growth and extension of plant cells. As stated in prior studies, these are self-assembled biopolymers formed by the association of EXT units, resulting in the ...
