Solubilization of covalently bound extensin from capsicum cell walls.
Acidified sodium chlorite cleaves isodityrosine and solubilizes covalently bound hydroxyproline-rich material from cell walls. This has been taken as evidence that isodityrosine acts as a cross-link holding the hydroxyproline-rich glycoprotein extensin in the cell wall. However, acidified chlorite was found to cleave peptide bonds in salt-soluble extensin and in bovine serum albumin (BSA). This...
متن کاملI-18: Avian Chimeras and Germ Cell Migration
Background: In avian species, the germ line stem cell population arises outside of the embryonic gonad and proceeds on a circuitous migration to the germinal epithelium. Specifically, in the avian embryo, the process of germ line stem cell migration proceeds through a series of active and passive migratory phases. The germline stem cells or primordial germ cells (PGCs) located in the epiblast o...
متن کاملA second extensin-like hydroxyproline-rich glycoprotein from carrot cell walls.
The insoluble extensin matrix of dicot cell walls has been studied most fruitfully by examining the salt-extractable precursors to this matrix. Multiple extensin-like hydroxyproline-rich glycoproteins (HRGPs) have been isolated, or their existence inferred, from tomato, potato, bean, soybean, melon, carrot, and other plants. We and others previously have studied a carrot extensin which we call ...
متن کاملRole of the extensin superfamily in primary cell wall architecture.
Nearly two centuries of progress have established the major components of the plant cell wall, a composite that includes interpenetrating networks of cellulose (Payen, 1838; Schulze, 1891), microfibrils (Frey-Wyssling et al., 1948; Preston et al., 1948), pectin (Braconnot, 1825) and lignin (Payen, 1838). However, only over the last five decades has a relatively minor hydroxyproline-rich structu...
متن کاملSolubilization and partial characterization of extensin fragments from cell walls of cotton suspension cultures. Evidence for a covalent cross-link between extensin and pectin.
Extensin, a major hydroxyproline (Hyp)-rich glycoprotein in walls of cultured cells of dicotyledonous plants, is very difficult to solubilize. To learn about the nature of the insolubilization, we have tested the ability of a variety of selective hydrolytic methods, and combinations of them, to liberate extensin or fragments of extensin from suspension-culture cell walls. After the complete deg...
