  1. aSee Additional File 1 for comments on classification of species into major eukaryotic groupings and accession numbers.
  2. bIsoelectric point calculated using the assumption that all residues have pKa values equivalent to that of isolated residues, so may not accurately represent the value for the folded protein.
  3. cIsotopically averaged molecular weight prediction in kiloDaltons.
  4. dThe BLASTP E-value (Expect value) measures the statistical significance threshold for protein sequence matches. The smaller the number the better the match. Computer shorthand nomenclature is used to present E-values when values are small. For example, 5e-01 = 0.5 and 5e-04 = 0.0005.
  5. eProteins were compared to Saccharomyces cerevisiae, Homo sapiens, Paramecium primaurelia, Trypanosoma brucei, Dictystelium discoideum, or Arabidopsis thaliana Vps25p by BLASTP. The Vps25 proteins used for comparison were chosen as the representive of fungal, metazoan, chromalveolate, excavate, amoebozoan, or plant species because these sequence are documented on the non-redundant protein database and they are well-known eukaryotic species.
  6. fWhen E-values were greater than 10, details are not provided.
  7. gA dash is used when alignments have 100% identity.
