  1. * Only those cases, for which there is a clear evidence of horizontal gene transfer and which are present in our databset, are shown.
  2. Ψ We predict that 14 more proteins in these families may have undergone horizontal gene transfer. However, there is no literature reference for these predictions.
  3. Θ RSp0782 is probably a false positive. Only small part of this sequence is included in this family.
