Fig 6. Hydrogen bonds varying in the presence or absence of C34 bound to FhCL1 (blue, top panel) and FhCL3 (orange, low panel).

Residues involved in hydrogen bonds (HB) are depicted in ball and sticks and colored by ΔOcc (delta of occupancy). ΔOcc is calculated with the formula ΔOcc = Occ FhCL—Occ FhCL_34 from the data in S5 and S6 Tables. HB are represented by black dashed lines. The catalytic Cys-His dyad is colored by atom.
