Sequence Communication: The amino acid sequence of protein AA from a burro (Equus asinus)

Abstract

The primary structure of amyloid fibril protein AA of a burro has been determined by Edman degradation. The 80 amino acid residue long protein shows strong resemblance to that of other mammalian AA-proteins and differs from equine protein AA at 5 positions: Burro/horse positions 20 (Q/N), 44 (R,Q, K/K,Q), 59 (G,L/C;,A), 61 (Q/E) and 65 (N/R).

Key Words:

• secondary amyloidosis
• protein AA
• primary structure
