Figure 2

Close-up view of the active site of cruzain: active sites of the structures of the complex of cruzain with MMTS (a) and of apocruzain (b). The electron density (2F obs − F calc) defining the catalytic residues of cruzain bound to MMTS (c) and apocruzain (d) is contoured at 1σ over the mean. Cartoon representations of cruzain bound to MMTS and apocruzain are shown in white and pink, respectively. Selected residues of the active site are highlighted as sticks. O, N and S atoms are colored red, blue and yellow, respectively. This figure was prepared using PyMOL.
