Descrição

Descrição geral

β-Casein from bovine milk is an immunoglobulin E (IgE)-binding epitope belonging to the secretory calcium-binding phosphoprotein family. It consists of 209 amino acids and five phosphate groups. β-Casein has a globular hydrophobic domain at the C-terminal, a highly solvated and charged domain at the N-terminal and proline residues.[1]

Aplicação

β-Casein from bovine milk has been used as a protein substrate in proteolytic assays.[2] It has also been used to embed polyacrylamide gels in β-casein zymography.[3]

It has been studied as a generator of peptides responsible for biological activities such as opiate, immunostimulating, antibacterial, and peptidase inhibitors.

Ações bioquímicas/fisiológicas

A polymorphic fraction of the major milk protein, casein. The A1 and B (but not A2) isoforms yield the bioactive peptide, ß-casomorphin upon gastrointestinal proteolytic digestion, which can have widely varied effects on human health. There is some effort to select dairy cattle for the A2 isoform to avoid this possibility.
