From: Functional classification of protein toxins as a basis for bioinformatic screening
Most of the 1600 singlet sequences can be related to highly populated clusters using multiple sequence alignments. For example, the first sequence is a cytotoxin associated protein from Heliobacter plyori included in cluster 4, the other three are from different clusters with only one sequence. Those sequences are almost identical to the first sequence, but contain deletions from 69 to 105, or at the C-termini.
