Figure 6From: 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 C (IrCC). The depictions of PCR primers, putative 20 AA signal peptide, four potential N-glycosylation sites and active site residues C256, H409, Q250 and N431 are as in Fig 4.Back to article page
