Predicted structure of the frog phosvitin component of Vitellogenin-A2 (1807 amino acids; Accession #P18709). The Protein Structure Prediction Server (PSIPRED) [16] was used to examine the possible conformation of the serine-rich phosvitin sequence (ca. 1126 - 1321). Line 1 indicates the confidence of the prediction, line 2 the relative position of each helix, line 3 whether the residue is part of a helix, strand or coil (see legend), and line 4 indicates the amino acid. Going from N- to C-terminal end, the sequence contains blocks of 38, 8, 28, 13 and 13 serine residues.
