Tryptase (EC 3.4.21.59) is the most abundant secretory granule-derived serine proteinase contained in mast cells and has been used as a marker for mast cell ...
Cell Wall Protein 2 (CWP2) is a cell mannoprotein that is covalently bonded to the cell wall and serves as a significant component of the cell wall structure. Generally, mannoproteins are special glycoproteins specifically in the outer part of the yeast cell wall and contributes to the yeast's ability to withstand acidic conditions in ...
The cell wall might have evolved to deter viral infections. Proteins embedded in cell walls are variable, contained in tandem repeats subject to homologous recombination. [17] An alternative scenario is that fungi started with a chitin-based cell wall and later acquired the GT-48 enzymes for the 1,3-β-glucans via horizontal gene transfer. The ...
Wall-associated kinases (WAKs) are one of many classes of plant proteins known to serve as a medium between the extracellular matrix (ECM) and cytoplasm of cell walls.They are serine-threonine kinases that contain epidermal growth factor (EGF) repeats, a cytoplasmic kinase and are located in the cell walls.

They form crosslinked networks in the young cell wall. Typically they have two major diagnostic repetitive peptide motifs, one hydrophilic and the other hydrophobic, with potential for crosslinking. Extensins are thought to act as self-assembling amphiphiles [3] essential for cell-wall assembly and growth by cell extension and expansion. The ...
Expansins characteristically cause wall stress relaxation and irreversible wall extension (). [15] This process is essential for cell enlargement. Expansins are also expressed in ripening fruit where they function in fruit softening, [16] and in grass pollen, [7] where they loosen stigmatic cell walls and aid pollen tube penetration of the stigmain germinating seeds for cell wall disassembly ...
Cellulose microfibrils are made on the surface of cell membranes to reinforce cells walls, which has been researched extensively by plant biochemists and cell biologist because 1) they regulate cellular morphogenesis and 2) they serve alongside many other constituents (i.e. lignin, hemicellulose, pectin) in the cell wall as a strong structural support and cell shape. [15]
Glutamate racemase (MurI) serves two distinct metabolic functions: primarily, it is a critical enzyme in cell wall biosynthesis, [2] but also plays a role in gyrase inhibition. [3] The ability of glutamate racemase and other proteins to serve two distinct functions is known as " moonlighting ".
