Tse3–Tsi3 interactions. (a) Insertion of three loops of Tsi3 (ribbon model in cyan), including two β-hairpins bridging β4–β5 and β7–β8 and a loop connecting β9 and α1, into the substrate-binding groove of Tse3 (surface representation in yellow). (b) The hydrogen-bond network formed between Tse3 (yellow) and Tsi3 (cyan) around the catalytic Glu residue in Tse3. The amino acids involved in hydrogen-bond formation are represented as stick models coloured by element.
