XSTREAM [73] was used to isolate unigenes coding for proteins with tandem-arranged repeat units. Unigenes in the D–T library (A), U–D library (B), and J–U library (C), with a coding region longer than 150 base pairs that were subjected to this analysis. As a control, shematrin family genes found in P.fucata were analyzed using XSTREAM (D). The identities of tandem-arranged repeat units are marked by numbers on the schematic at the top left of each motif (red font). The copy number of repeat units is shown on the top right of the motif (black font). On the top of each motif there is a label of identity*copy number. Bars = 50 amino acids (in A, B, C, D).
