2000 journal article

Antigenicity of casein phosphopeptides prepared with immobilized glutamic acid-specific endopeptidase or trypsin

NUTRITION RESEARCH, 20(3), 359–370.

By: O. Park n & J. Allen n

author keywords: alpha(s)-casein; beta-casein; casein phosphopeptides; antigenicity
TL;DR: The results suggest that tryptic phosphopeptides could be used as a food ingredient with hypoallergenicity, and significantly less antigenic than intact α s -casein and its hydrolysates. (via Semantic Scholar)

1998 journal article

Preparation of phosphopeptides derived from alpha(s)-casein and beta-casein using immobilized glutamic acid-specific endopeptidase and characterization of their calcium binding

JOURNAL OF DAIRY SCIENCE, 81(11), 2858–2865.

By: O. Park n & J. Allen n

author keywords: casein phosphopeptides; immobilized enzyme; glutamic acid-specific endopeptidase; calcium binding
MeSH headings : Amino Acid Sequence; Animals; Binding Sites; Caseins / chemistry; Caseins / metabolism; Chromatography, Ion Exchange; Electrophoresis, Polyacrylamide Gel; Endopeptidases / metabolism; Enzymes, Immobilized; Hydrolysis; Milk / chemistry; Molecular Sequence Data; Molecular Weight; Peptide Fragments / chemistry; Peptide Fragments / isolation & purification; Peptide Fragments / metabolism; Phosphopeptides / chemistry; Phosphopeptides / isolation & purification; Phosphopeptides / metabolism; Potassium Chloride
TL;DR: Phosphopeptides that were derived from α s -CN or β -CN were prepared with immobilized glutamic acid-specific endopeptidase, and their Ca 2+ binding was characterized, and casein phosphopeptide content of the elution profile was monitored by analysis of protein and P concentrations.

1997 journal article

Immunogenicity of casein phosphopeptides derived from tryptic hydrolysis of beta-casein

JOURNAL OF DAIRY SCIENCE, 80(9), 1971–1976.

By: R. Heddleson n, O. Park n & J. Allen n

author keywords: beta-casein; casein phosphopeptides; immunogenicity
MeSH headings : Animals; Antibody Formation; Caseins / immunology; Caseins / metabolism; Enzyme-Linked Immunosorbent Assay; Female; Hydrolysis; Immunoglobulin E / blood; Immunoglobulin G / blood; Milk Proteins / immunology; Peptide Fragments / immunology; Peptide Fragments / metabolism; Peritoneum / immunology; Phosphoproteins / immunology; Rats; Rats, Sprague-Dawley; Trypsin / metabolism
TL;DR: The immunogenicity of phosphopeptides derived from tryptic hydrolysis of beta-casein (CN) was investigated in a rat model system and it is suggested that immunogensicity of the phosphopePTides was reduced compared with that of native beta-CN and skim milk proteins. (via Semantic Scholar)
