Figure 1
Two views of solvent channels in hexagonal thermolysin. (a) View down the c axis by displaying symmetry mates as backbone traces in COOT. A single protein and the unit-cell outline are both shown in yellow. There are two apparent pores of radii 4 and 1.5 Å. (b) Distance map view contoured at 6 Å. The c axis runs up–down. Two entwined helical pores are visible. The larger helical pore (radius 11.5 Å) when projected along the c axis yields the apparent 4 Å pore in (a). |
