Sticholysins are pore‐forming toxins produced by the sea anemone Stichodactyla helianthus. When they encounter a sphingomyelin‐containing membrane, these proteins bind to it and oligomerize, a process that ends in pore formation. Mounting evidence indicates that StnII can favour the activity of StnI. Previous results have shown that these two isotoxins can oligomerize together. Furthermore, StnII...
The three-dimensional structures of the α-sarcin ribotoxin and its Δ(7–22) deletion mutant, both complexed with a 20-mer oligonucleotide mimicking the sarcin/ricin loop (SRL) of the ribosome, have been docked into the structure of the Halobacterium marismortui ribosome by fitting the nucleotide atomic coordinates into those of the ribosomal SRL. This study has revealed that two regions of the ribotoxin,...
