Crystallization (Commentary)

Crystallization (Comment)	Organism
cyanide-inhibited MhuD in complex with heme as well as detailed characterization of this species. There is no evidence for an ordered network of water molecules on the distal side of the heme substrate. The degree of heme ruffling in the crystal structure is greater than that observed for heme oxygenases and less than that observed for heme-degrading enzyme IsdI. The Fe 3dxz-, 3dyz-, and 3dxy-based molecular orbitals are very close in energy, and the room-temperature 1H NMR spectrum is consistent with population of both a 2Eg electronic state with a (dxy)2(dxz,dyz)3 electron configuration, and a 2B2g state with a (dxz,dyz)4(dxy)1 electron configuration. MhuD-heme-CN has a 2B2g electronic ground state with a low-lying 2Eg excited state	Mycobacterium tuberculosis
