title: Amino acid sequence of horseshoe crab, Tachypleus tridentatus, striated muscle troponin C.
abstract: The amino acid sequence of troponin C obtained from horseshoe crab, Tachypleus tridentatus, striated muscle was determined by sequence analysis and alignments of chemically and enzymatically cleaved peptides. Troponin C is composed of 153 amino acid residues with a blocked N-terminus and contains no tryptophan or cysteine residue. The site I, one of the four Ca2+-binding sites, is considered to have lost its ability to bind Ca2+ owing to the replacements of certain amino acid residues.
