Figure 3
TtLMCO1 copper sites. Copper ions in the TNC (left) are shown as brown spheres and are coordinated by histidine residues shown as wheat and magenta sticks. A dioxygen molecule is located between the T3 coppers, and a water molecule (W1) is modelled next to the T2 copper ion. Coordination bonds are shown as grey dashed lines, while the electrostatic interaction of W1 with T2 is shown as a marine dashed line. His558, Cys559 and His560, which form the `histidine bridge' that enables electron transfer from the T1 copper site to the TNC, are shown as magenta sticks. |
