Purification, characterization and immobilization of proteinase inhibitors from Stichodactyla helianthus

Toxicon, 1996
Isolation of proteinase inhibitors from the sea anemone Stichodactyla helianthus was achieved by trichloroacetic acid treatment of the aqueous extract followed by affinity chromatography on trypsin-Sepharose and ion-exchange chromatography on CM-cellulose. The average molecular mass of the major inhibitor (ShPI-I) obtained by fast atom bombardment mass

Purification and characterization of two hemolysins from Stichodactyla helianthus

Toxicon, 2001
Two hemolysins, Sticholysin I (St I) and Sticholysin II (St II) were purified from the sea anemone Stichodactyla helianthus combining gel filtration and ion exchange chromatography. The amino acid composition of both cytolysins was determined revealing a high proportion of glycine, lysine, tyrosine and non-polar amino acids (alanine, leucine and valine)

Stichodactyla helianthus Peptide, a Pharmacological Tool for Studying Kv3.2 Channels

Molecular Pharmacology, 2005
Voltage-gated potassium (Kv) channels regulate many physiological functions and represent important therapeutic targets in the treatment of several clinical disorders. Although some of these channels have been well-characterized, the study of others, such as Kv3 channels, has been hindered because of limited pharmacological tools. The current study was

Characterization of a potassium channel toxin from the Caribbean sea anemone Stichodactyla helianthus

Toxicon, 1995
A peptide toxin, ShK, that blocks voltage-dependent potassium channels was isolated from the whole body extract of the Caribbean sea anemone Stichodactyla helianthus. It competes with dendrotoxin I and alpha-dendrotoxin for binding to synaptosomal membranes of rat brain, facilities acetylcholine release at an avian neuromuscular junction and suppresses

Identity between cytolysins purified from two morphos of the Caribbean sea anemone Stichodactyla helianthus

Toxicon, 2002
Stichodactyla helianthus is a sea anemone relatively abundant along Cuban coasts appearing in two morphos with different colors in their tentacles: green or brownish, probably due to their association with algal symbionts. Traditionally, the brownish morpho has been used as a source of sticholysins I and II, the most characterized cytolysins from this ...

Chemical synthesis of a neurotoxic polypeptide from the sea anemoneStichodactyla helianthus⁺

International Journal of Peptide and Protein Research, 1990
The sea anemoneStichodactyla helianthusneurotoxin I, a 48‐residue polypeptide, was synthesized by automated solid phase methodology. The fully reduced polypeptide was subsequently refolded in the presence of a glutathione oxidoreduction buffer to the biologically active species containing three disulfide bonds.

An ouabain-sensitive Na+,K+-ATPase in tentacles of the sea anemone Stichodactyla helianthus

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1995
Tentacles of Stichodactyla helianthus contain an ouabain-inhibitable, (Na+,K+)-stimulated ATPase. The K0.5 for Na+ was 24 mM and for K+, 3.2 mM. The apparent affinity for ouabain was low, I50 = 10(-4) M. The order of cation affinities was Rb+ > K+ > NH4+ = Cs+.

Primary structure of two cytolysin isoforms from Stichodactyla helianthus differing in their hemolytic activity.

Toxicon, 2001
Sticholysin I (St-I) and sticholysin II (St-II) are cytolysins purified from the sea anemone Stichodactyla helianthus with a high degree of sequence identity (93%) but clearly differenced in their hemolytic activity. In order to go further into the structural determinants for the different behavior of St-I and St-II, we report here the complete amino ...
