Notably, except PvShK, the ShK toxin (P29187) originated from Stichodactyla helianthus is most equivalent to PcShK3.Figure 1. Multiple sequence alignment and phylogenetic analysis of PcShK3 from P. caribaeorum. (A)PcShK3 and its homologs from other species of marine organisms were chosen for several sequence alignment and phylogenetic evaluation. From the Maximumlikelihood tree (Figure 1C), it is actually seen that PcShK3 clusters nicely with all the ShK toxin of Protopalythoa variabilis, which was predicted from other zoantharian transcriptomes from our prior study [23]. Also, PcShK3 is phylogenetically connected to KappastichotoxinShe3a (UniProt ID: P21987). PcShK3 is usually grouped with members of your form 1 sea anemone toxins, every single of which consists of a cysteine framework equivalent to that on the ShK toxin from the Stichodactyla helianthus sea anemone.

From the Maximumlikelihood tree (Figure 1C), it is observed that PcShK3 clusters properly with the ShK toxin of Protopalythoa variabilis, which was predicted from other zoantharian transcriptomes from our preceding study [23]. Also, PcShK3 is phylogenetically amino acids, containing six hugely conserved cysteine residues.can be grouped with members of are therefore connected to KappastichotoxinShe3a (UniProt ID: P21987).
