Fig. 7

Tertiary structure model and schematic diagram of the CgSS active site. a Cartoon display of the three-dimensional structure of CgSS and five conserved domains (I: red, II: green, III: blue, IV: yellow, V: magenta). b Schematic diagram showing the active site of CgSS (green ellipse) and five amino acid residues (D77, D81, Y168, D213, and D217; red dots).) The figures were performed using the Swiss Model (https://www.swissmodel.expasy.org) and the PyMOL software based on the the crystal structure of Trypanosoma cruzi SS (Template 3wca.3.A, with sequence identity of 46.02%, the ranges from E34–S370)
