Structural and functional characterization of sticholysin III: A newly discovered actinoporin within the venom of the sea anemone Stichodactyla helianthus. [PDF]

Archives of Biochemistry and Biophysics, 2020
Actinoporins are a family of pore-forming toxins produced by sea anemones as part of their venomous cocktail. These proteins remain soluble and stably folded in aqueous solution, but when interacting with sphingomyelin-containing lipid membranes, they ...

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 ...

The NMR solution structure of a Kunitz‐type proteinase inhibitor from the sea anemone Stichodactyla helianthus

European Journal of Biochemistry, 1993
The solution structure of a 55‐amino‐acid Kunitz‐type proteinase inhibitor, ShPI, purified from the Caribbean sea anemone Stichodactyla helianthus, was determined by NMR spectroscopy. Nearly complete sequence‐specific 1H‐NMR assignments were obtained at pH 4.6 and 36°C, and stereospecific assignments were determined for 23 pairs of diastereotopic ...

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+.
