Rat intestinal glycoprotein lowering bactericidal activity of serum on 32P-labelled E. coli. 1976

R Winsnes, and T Midtvedt, and A Trippestad

A glycoprotein fraction, by which the 32P-releasing activity of serum on labelled E. coli is lowered, was isolated from caecum content of germfree rats. The glycoprotein contained 83.1% sulphate, and 16.1% protein. The molecular weight ranged from 3.2 X 10(5) to 2.4 X 10(6), and the iso-electric point from pH 0.9 to 3.0. Physiologically, it may play a role in the interaction(s) between the host and its intestinal flora.

UI	MeSH Term	Description	Entries
D007413	Intestinal Mucosa	Lining of the INTESTINES, consisting of an inner EPITHELIUM, a middle LAMINA PROPRIA, and an outer MUSCULARIS MUCOSAE. In the SMALL INTESTINE, the mucosa is characterized by a series of folds and abundance of absorptive cells (ENTEROCYTES) with MICROVILLI.

D007525	Isoelectric Focusing	Electrophoresis in which a pH gradient is established in a gel medium and proteins migrate until they reach the site (or focus) at which the pH is equal to their isoelectric point.	Electrofocusing,Focusing, Isoelectric

D009005	Monosaccharides	Single chain carbohydrates that are the most basic units of CARBOHYDRATES. They are typically colorless crystalline substances with a sweet taste and have the same general formula CnH2nOn.	Monosaccharide,Simple Sugar,Simple Sugars,Sugar, Simple,Sugars, Simple
D009077	Mucins	High molecular weight mucoproteins that protect the surface of EPITHELIAL CELLS by providing a barrier to particulate matter and microorganisms. Membrane-anchored mucins may have additional roles concerned with protein interactions at the cell surface.	Mucin
D009439	Neuraminidase	An enzyme that catalyzes the hydrolysis of alpha-2,3, alpha-2,6-, and alpha-2,8-glycosidic linkages (at a decreasing rate, respectively) of terminal sialic residues in oligosaccharides, glycoproteins, glycolipids, colominic acid, and synthetic substrate.

D001770	Blood Bactericidal Activity	The natural bactericidal property of BLOOD due to normally occurring antibacterial substances such as beta lysin, leukin, etc. This activity needs to be distinguished from the bactericidal activity contained in a patient's serum as a result of antimicrobial therapy, which is measured by a SERUM BACTERICIDAL TEST.
