Homology modelling of Bp-XylX-1, Bp-XylX-2, and Lr-XylC β-xylosidases. Homology modelling of β-xylosidases from L. reuteri ATCC 53608 and B. producta ATCC 27340 was based on PDB ID: 3VSU of Ts-XOS using Phyre2. Bp-XylX-1 (A), Bp-XylX-2 (B), and Lr-XylC (C) are superimposed onto 3VSU (cyan). Catalytic nucleophile (Asp-D) and proton donor (Glu-E) were identified in Bp-XylX1 (D), Bp-XylX2 (E), and Lr-XylC (F) on the basis of 3VSU (green). Homology modelling was performed in PyMOL.
