• PubMed Abstract: 
  

  Sticholysin I is an actinoporin, a pore forming toxin, of 176 aminoacids produced by the sea anemone Stichodactyla heliantus. Isotopically labelled (13)C/(15)N recombinant protein was produced in E. coli. Here we report the complete NMR (15)N, (13)C and (1)H chemical shifts assignments of Stn I at pH 4.0 and 25 degrees C (BMRB No. 15927).
