Figure 4. Enzyme and lactose substrate docking at the center catalytic site of GH 1 from C. maquilingensis monomer. (a) Cartoon representation showing lactose in sticks representation. (b) Molecular surface representation showing lactose (pink colour) buried in the catalytic pocket (red oval) at the center of monomer, the radial tunnel with two openings on the sides is also visible
