title: The amino acid sequence of an amyloid fibril protein AA isolated from the horse.
abstract: The amino acid sequence of the amyloid fibril protein AA from horse was established from characterization of cyanogen bromide fragments, tryptic peptides, and a peptide derived from a digest with Staphylococcus aureus V8 proteinase. The protein was found to consist of 80 amino acid residues. Sequence homologies with protein AA from other species were very striking, and revealed an insertion of two amino acid residues between positions 72 and 73. In position 44, two amino acid residues were found which provide further evidence for a polymorphism in the amyloid fibril protein AA.
