We identified two ice-binding protein (IBP) sequences, named EFsymbAFP and EFsymbIBP, from a putative bacterial symbiont of the Antarctic psychrophilic ciliate Euplotes focardii. EFsymbAFP is 57,43% identical to the antifreeze protein (AFP) from the Stigmatella aurantiaca strain DW4/3-1, which was i...
