Figure 6From: Identification of novel aspartic proteases from Strongyloides ratti and characterisation of their evolutionary relationships, stage-specific expression and molecular structureA putative novel disulphide bond in S. ratti ASP-2A. Comparison of human pepsin template (PDB code 1pso; [44]) and ASP-2A model in the vicinity of the ASP-2A-specific novel putative disulphide bond. The figure was produced using PyMOL [49], as were Figures 8 and 9.Back to article page
