Molecular characterization and functional analysis of serine/threonine protein phosphatase of Toxocara canis

This figure represents the structural organization of the predicted Tc STP polypeptide. (A) The complete 1192-bp cDNA sequence contains an uninterrupted 942-nucleotide ORF (313 amino acids) encoded by nucleotide positions 118-1059 (green area) of the gene. (B) The predicted polypeptide contains the conserved signature sequence motifs, GDXHG, GDXVDRG, GNHE, HGG, RG, and H of the PPP family and metal ion binding sites in catalytic domain at Asn-122; Asp-62 and -90; and H-64, -172, and -247 (Online color).
