Genetic variants of a protein differ from each other only by a few amino acids. The three subgroups have in common the fact that one of two amino acids containing hydroxy groups are esterified to phosphoric acid.

WebCasein micelles are covered with a negatively-charged “hairy” layer of κ-casein. In milk, these casein micelles float around and bounce off each other. Those κ-casein hairs get in the way and prevent the casein from sticking and aggregating. Our goal in cheese making is to make those casein micelles stick together somehow. Κ-casein, or kappa casein, is a mammalian milk protein involved in several important physiological processes. Chymosin (found in rennet) splits K-casein into an insoluble peptide (para kappa-casein) and water-soluble glycomacropeptide (GMP). GMP is responsible for an increased efficiency of digestion, … Vedeți mai multe Caseins are a family of phosphoproteins (αS1, αS2, β, κ) that account for nearly 80% of bovine milk proteins and that form soluble aggregates are known as "casein micelles" in which κ-casein molecules stabilize the … Vedeți mai multe Κ-casein labeled with the fluorochrome fluorescein isothiocyanate (FITC) to yield the fluorescein thiocarbamoyl (FTC) derivative. … Vedeți mai multe • InterPro: IPR000117 Kappa casein • Fluorescein Thiocarbamoyl-Kappa-Casein Assay for the Specific Testing of Milk-Clotting Proteases Vedeți mai multe Chymosin (EC 3.4.23.4) is an aspartic protease that specifically hydrolyzes the peptide bond in Phe105-Met106 of κ- casein and is considered to be the most efficient protease for the cheesemaking industry.
