Figure 2

Site of TTQ formation in MADH. (A) 2Fo-Fc electron density for the MauG-preMADH complex (resolution 2.1 Å). (B) The first 2Fo-Fc electron density calculated with MauG-preMADH + H2O2 structure factors (resolution 2.1 Å) and MauG-preMADH model phases with the preMADH βTrp57 and βTrp108 side-chains omitted. Electron densities were contoured at 1 σ. Carbon coloring: preMADH, light green; preMADH + H2O2, dark green. Figure produced using PyMOL (http://www.pymol.org/).
