Figure 3

Structural models of β-glucosidases characterised in this work: LAB25g2 ( A and B, ) SRFg14 ( C and D), SRFg18 ( E and F ) and LAB20g4 ( G and H). Panels A, C, E and G show overall representation of the enzyme structures. The three protein domains, α/β barrel, α/β sandwich and fibronectin-like, are coloured green, yellow and blue, respectively. Panels B, D, F and H show closeup of the catalytic centres, indicating the position of the catalytic nucleophile (Asp) and proton donor (Glu).
