Figure 5From: Profiling of proteolytic enzymes in the gut of the tick Ixodes ricinus reveals an evolutionarily conserved network of aspartic and cysteine peptidasesNucleotide and deduced amino acid sequence of Ixodes ricinus cathepsin L (IrCL). The depictions of PCR primers, putative 16 AA signal peptide, two potential N-glycosylation sites and active site residues C143, H262, Q137 and N282 are as in Fig 4.Back to article page
