Amino-Acid Sequence of Toxin I from Anemonia sulcata

The Stimulus to Feeding in Anemonia Sulcata

Amino acid sequence of a deltalike toxin from Staphylococcus epidermidis.

A deltalike toxin produced by a clinical isolate of Staphylococcus epidermidis was purified, and the amino acid sequence was determined. The toxin molecule consisted of 25 amino acid residues and shared a high degree of molecular homology with delta toxin purified from a Staphylococcus aureus human isolate.

Amino 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...

Amino 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...

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...
