The active site of SmTetX is located at the re site. (a) Composition of the active site in combined stick and secondary-structure representation. C atoms of the substrate-binding domain are coloured red, those of the FAD-binding domain green and those of the C-terminal helix blue. The chloride anion is shown as a yellow sphere. (b, c) Alignment of SmTetX with the TetX–chlortetracycline (CTC) complex (Volkers et al., 2011 ▸; PDB entry 2y6r) in yellow shown in stick representation. The r.m.s.d. was 3.74 Å using 284 Cα atoms of chains A. The graphics were prepared in PyMOL 2.5 (Schrödinger).
