Amino acid sequence of crayfish troponin I.
Troponin I is the actomyosin ATPase inhibitory subunit present in the thin filament regulatory complex. The complete amino acid sequence of crayfish tail muscle troponin I has been determined. The protein is composed of 201 amino acid residues and has a molecular weight of 23,547. The N terminus is blocked, likely by an acetyl group. Crayfish troponin I shows a rather low (20-25%) sequence iden...
متن کاملAmino acid sequence of porcine neurophysin-I.
Tryptic and chymotryptic peptide fragments obtained from performic acid-oxidized porcine neurophysin-I were isolated and purified by gel filtration, ion exchange chromatography, paper electrophoresis, and paper chromatography. The larger tryptic peptides were further hydrolyzed by papain, chymotrypsin, pepsin, or HCl to yield shorter fragments amenable to Edman degradation. The sum of the compo...
متن کاملSynthetic studies on the inhibitory region of rabbit skeletal troponin I. Relationship of amino acid sequence to biological activity.
Twelve peptide analogs of the actomyosin ATPase inhibitory region of rabbit skeletal troponin I (Tn-I) have been synthesized by the solid phase method and tested for biological activity in both actomyosin and acto-S1(A1) systems. Acto-S1(A1) is a cleaner and more facile system and we found no important discrepancies in the results for the two systems. These studies indicate that the sequence 10...
متن کاملAmino acid sequence of neurotoxin I from Centruroides sculpturatus Ewing.
The further characterization of toxin I from venom of the scorpion Centruroides sculpturatus Ewing (region, Southwestern United States) is reported. Toxin I is a single palypeptide chain of 64 amino acid residues crosslinked by four disulfide bridges. The complete amino acid sequence of toxin I was deduced from the sequence of its tryptic peptides and overlaps provided by its chymotryptic pepti...
متن کاملAmino-acid sequence of tropomyosin-binding component of rabbit skeletal muscle troponin.
The complete amino-acid sequence of rabbit skeletal troponin-T is reported. The protein consists of a single polypeptide chain of 259 amino acids; it has an acetylated amino terminus and a molecular weight of 30,503. The sequence was determined by manual and/or automated Edman degradation techniques on the six fragments obtained after cleavage with cyanogen bromide. The larger fragments were fu...
