The physical properties of the NH₂-terminal deleted mouse cardiac TnTs (McTnT-ND₇₂ and McTnT-ND₉₁), embryonic (Emb McTnT, TnT-1) and adult (Adult McTnT, TnT4) mouse cardiac TnTs (31), Acidic and Basic model TnT chimeras and chicken fast skeletal muscle TnT3 and TnT4 (accession number J04198) were calculated from amino acid sequences.
