Biochemical characterization of the bovine genetic K-casein C and E variants

Summary Analysis of elution profiles of enzymatic and CNBr digests of K-caseins C and E, and sequencing of most relevant peptides allowed the chemical characterization of both genetic variants. They differ from their B and A allelic counterparts by a single substitution, His97/Arg and Gly155/Ser, respectively. Electrophoretic behaviour of the investigated C and E variants was in good agreement with the observed amino acid replacements.
