  • Title: Amino-acid sequence of the short subfragment-2 in adult chicken skeletal muscle myosin.
    Author: Watanabe B.
    Journal: Biol Chem Hoppe Seyler; 1989 Jun; 370(6):549-58. PubMed ID: 2775482.
    Abstract:
    The amino-acid sequence of a short subfragment-2 in the amino-terminal portion of subfragment-2 (S-2) derived from adult chicken skeletal muscle myosin was completely determined. Peptides cleaved by cyanogen bromide and by lysyl endopeptidase of S-carboxymethylated S-2, and hydrolytic peptides obtained with trypsin or dilute acetic acid of larger CNBr fragments were isolated and sequenced. This region was composed of 257 amino-acid residues, and hydrophobic and charged residue repeat units were found highly conserved and with a periodicity in 7 or 28 residues. This sequence of the short S-2 fragment of chicken skeletal muscle myosin was compared with the sequence of chicken and rat embryonic skeletal muscle myosins, rabbit skeletal and rabbit cardiac muscle myosin (alpha-myosin heavy chain), and 95.3%, 86.8%, 89.9% and 94.2% sequence identities were observed, respectively.
