A small camel-milk protein rich in cysteine/half-cystine

A small protein (Mr about 14 000) rich in cysteine/half-cystine has been isolated from camel milk by exclusion chromatography and reverse-phase high-performance liquid chromatography. The N-terminal amino acid sequence shows a region with several positional identities with alpha and beta-caseins, wh...

Zusammenfassung:A small protein (Mr about 14 000) rich in cysteine/half-cystine has been isolated from camel milk by exclusion chromatography and reverse-phase high-performance liquid chromatography. The N-terminal amino acid sequence shows a region with several positional identities with alpha and beta-caseins, which however lack cysteine residues; positions 16-20 are identical and involve the serine residues that have been found to be phosphorylated in beta-caseins.
