Abstract
The amino acid sequence of equine .alpha.-lactalbumin was determined with the aid of an automatic sequencer. The protein chain consists of 123 amino acids and has a MW of 14218. Elucidation of the structure involved sequence determination of native protein (residues 1-32), cyanogen bromide fragments and tryptic, chymotryptic and Staphylococcus aureus V8 proteolytic peptides. Approximately 67% of the residues are identical with corresponding residues of bovine .alpha.-lactalbumin B, and there is close homology with .alpha.-lactalbumin of other species.
