Figure 7From: Identification of novel aspartic proteases from Strongyloides ratti and characterisation of their evolutionary relationships, stage-specific expression and molecular structureCartoon view of the final ASP-2A model coloured according to secondary structure (yellow β-strand, red α-helix and green irregular). For the purposes of orientation, the inhibitor from superimposed mouse renin template is shown as purple sticks. Catalytic aspartic acid residues are shown as cyan and red sticks and disulphide bonds as dark blue sticks. Side chains that differ in ASP_2B are shown as orange (near catalytic site) or grey (elsewhere) sticks.Back to article page
