Isolation and complete amino acid sequence of a basic low molecular weight protein from black swan egg white. 1983

R J Simpson, and F J Morgan

The following complete amino acid sequence of a low molecular weight basic protein (Mr 4,454) from black swan egg white has been determined: less than Glu-Val-Arg-Lys-Tyr-Cys-Pro-Lys-Val-Gly-Tyr-Cys-Ser-Ser-Lys-Cys-Ser-Lys-Ala-Asp-Val-Trp-Ser-Leu-Ser-Ser-Asp-Cys-Lys-Phe-Tyr-Cys-Cys-Leu-Pro-Pro-Gly-Trp-Lys. There is significant homology between this protein, provisionally designated cygnin, and the NH2-terminal region of the second domain of chicken ovotransferrin. The disulfide bonds have not been assigned; however, the arrangement of half-cystines in cygnin is sufficiently different from that of the known transferrins to suggest that cygnin is derived from another gene.
