Fig. 4From: Identification, isolation, and cloning of the full-length sequence of a gene encoding trypsin inhibitor-like protein (TIL) secreted by the intestinal parasitic nematode Strongyloides rattiCLUSTAL multiple sequence alignment by MUSCLE (3.8) of selected 16 aa sequences of TIL domains in some nematodes (including the Sra-TIL domain which is highlighted in gray) and arthropods. Samples are labeled according to the GenBank accession numbers (left) and name of species (right). Symbols: identical (asterisks; black highlighted) and no aa (dashes). The active inhibitory site is labeled with red boundaryBack to article page
