a
Data for EcSWP1, EiSWP1, and EiSWP2 have been described previously (5, 15). The predicted amino acid sequences for EcSWP1, EiSWP1, and EiSWP2 were obtained from accession no. CAD25337, AAL27283, and AAL27282, respectively.
b
The mature proteins correspond to polypeptides devoid of predicted N-terminal signal peptide.
c
The pI, amino acid percentages, and number of O-glycosylation potential sites are deduced from the mature proteins.
