Structural studies on colanic acid, the common exopolysaccharide found in the enterobacteriaceae, by partial acid hydrolysis. Oligosaccharides from colanic acid.
The exopolysaccharide slime colanic acid has been isolated from representative strains of Escherichia coli, Salmonella typhimurium and Aerobacter cloacae. Analysis showed that each polymer contained glucose, galactose, fucose and glucuronic acid, together with acetate and pyruvate. The molar proportions of these components were 1:1.8:1.9:1:1:1 approximately. On the basis of periodate oxidation ...
متن کاملPeptides Obtained by Peptic Hydrolysis of Performic Acid-oxidized Ribonuclease
In a continuation of the structural studies on ribonuclease reported in earlier papers (l-3), the products resulting from the action of pepsin on performic acid-oxidized ribonuclease have been examined by means of ion exchange chromatography. Eight peptides have been isolated in purified form and their amino acid compositions have been determined. In a following communication (4), a partial str...
متن کاملPeptides obtained by tryptic hydrolysis of performic acid-oxidized ribonuclease.
In the present study, the chemical structure of ribonuclease has been investigated by the use of trypsin as a reagent. for the hydrolysis of specific peptide bonds in the oxidized protein, and the resulting peptides have been separated and analyzed by ion exchange chromatography. The investigations of Anfinsen, Redfield, Choate, Page, and Carroll (3) have shown that ribonuclease consists of a s...

متن کاملAntimicrobial Peptides Derived from Goat’s Milk Whey Proteins Obtained by Enzymatic Hydrolysis
In this study the bacterial growth inhibitory activity of peptide fragments produced from goat’s milk whey proteins by enzymatic hydrolysis using trypsin, ficin and a combination of both was investigated. Goat’s milk whey proteins were isolated and subjected to enzymatic hydrolysis and peptides were purified by ultrafiltration followed by reverse-phase high-performance liquid chromatography (RP...
