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

Interfacial activity of an ion channel-generating protein cytolysin from the sea anemone Stichodactyla helianthus

Toxicon, 1989
The ability of a purified sea anemone (Stichodactyla helianthus) protein cytolysin to interact with a variety of interfaces was investigated by means of the Wilhemy plate method. At the air:water and lipid:water interfaces, the toxin lowered the surface pressure most readily as the aqueous phase pH increased towards the isoelectric point (9.8) of the ...

Inmunolocalización de citolisinas en la anémona de mar (Stichodactyla helianthus)

, 2010
Las sticholisinas I y II son dos proteínas citolíticas provenientes de la anémona de mar (Stichodactyla helianthus) que presentan un gran potencial biomédico. La ubicación de estas citolisinas dentro del tejido del animal sería un elemento de gran utilidad en el estudio de las funciones para las cuales este las emplea y facilitaría el proceso de ...

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

Stycholysin II, a cytolysin from the sea anemone Stichodactyla helianthus promotes higher hemolysis in aged red blood cells

Toxicon, 2008
We have investigated the relationship between the status of red blood cells (RBCs) and their susceptibility to toxin sticholysin II (StII) hemolytic activity; we have evaluated this effect in different RBC ensembles, comprising young and old cells, and in cells partially damaged by their pre-exposition to a free radical source.
