It is often found attached to proteins, and the resulting arabinogalactan protein (AGP) functions as both an intercellular signaling molecule and a glue to seal plant wounds. [1] The microbial arabinogalactan is a major structural component of the mycobacterial cell wall. [2] [3] Both the arabinose and galactose exist solely in the furanose ...
Arabinogalactan-proteins (AGPs) are highly glycosylated proteins (glycoproteins) found in the cell walls of plants. Each one consists of a protein with sugar molecules attached (which can account for more than 90% of the total mass). They are members of the wider class of hydroxyproline (Hyp)-rich cell wall glycoproteins, a large and diverse ...
The first has between 28 and 46 carbon atoms with either 0 or 1 unsaturated bonds. The second has between 34 and 54 carbon atoms with between 0 and 4 unsaturated bonds. Sutcliffe (1998) has proposed that they are linked to the rest of the cell wall by arabinogalactan molecules.
Arabinogalactan endo-β-1,4-galactanase (EC 3.2.1.89, endo-1,4-β-galactanase, galactanase, arabinogalactanase, ganB (gene)) is an enzyme with systematic name ...
In biology, the extracellular matrix (ECM), [1] [2] also called intercellular matrix (ICM), is a network consisting of extracellular macromolecules and minerals, such as collagen, enzymes, glycoproteins and hydroxyapatite that provide structural and biochemical support to surrounding cells.
Satellite glial cells are a type of glia found in the peripheral nervous system, specifically in sensory, [2] sympathetic, and parasympathetic ganglia. [3] They compose the thin cellular sheaths that surround the individual neurons in these ganglia. In a SGC, the cell body is denoted by the region containing the single, relatively large nucleus ...
Arginylglycylaspartic acid (RGD) is the most common peptide motif responsible for cell adhesion to the extracellular matrix (ECM), found in species ranging from Drosophila to humans. Cell adhesion proteins called integrins recognize and bind to this sequence, which is found within many matrix proteins, including fibronectin, fibrinogen ...
Specifically, they recognize cell-surface glycoconjugates containing sialic acid on the surface of host red blood cells with a low affinity and use them to enter the endosome of host cells. [6] Hemagglutinins tend to recognize α-2,6-linked sialic acids of the host cells in humans and α-2,3-linked sialic acids in avian species, although there ...
