Figure 1
Stereodiagram and ribbon drawing of the heme group in HEC (subunit A). The residues Arg354 and Tyr358 on the proximal side and His75 and Asn148 on the distal side as well as the substrate water are shown. The electron-density map was calculated using DM phase angles and contoured at the 1.5σ level. The programs TOM, MOLSCRIPT and Raster3D were used in making this figure.
