title: Sequences of the soluble tryptic peptides from myoglobin of yellowfin tuna (Thunnus albacares).
abstract: 1. Amino acid sequences of the soluble tryptic peptides of yellowfin tuna myoglobin, comprising 60% of the total residues, are presented. 2. The amino terminus is acetylated as shown by Fourier transform nuclear magnetic resonance spectroscopy of an N-terminal dipeptide. 3. Comparison of peptide sequences from yellowfin tuna myoglobin with corresponding regions of mammalian myoglobins shows obvious homology around the heme-attachment site and the carboxyl terminus, but marked dissimilarity is evident at other locations, such as the amino terminal region.
