Figure 2. Structural comparison of P115A with wild-type Tt H-NOX.

Figure 2

The heme in P115A (silver) is flatter than wild-type (gold). Significant translations are observed in the N-terminal region of the heme-flattened P115A crystal structure. Shown are molecule A from the monoclinic crystal structure of wild-type H-NOX and molecule D from the P115A crystal structure.
