22 proteins described in the paper have not been predicted as suitable candidates for GPI anchoring:

  1. We could not detect a suitable omega-site for 7 proteins:

  2. orf19.7517.prot
    orf19.4377.prot
    orf19.2108.prot (S<0)

    orf19.2033.prot
    orf19.6336.prot (S<0)
    orf19.2910.prot

  3. In further 2 proteins a typical spacer region is missing:

  4. orf19.6784.prot
    orf19.1616.prot (S<0)

  5. 8 proteins lack an appropriately constructed hydrophobic tail:

  7. 5 sequences are non-compatible with our prediction function at all:

  8. orf19.1816.prot (*) The sequence of orf19.2355 is given in the paper. This sequence is already included in the set and is predicted as suitable candidate for GPI anchoring.
