Nitric oxide (NO) is an important signaling molecule that is involved in a wide range of
physiological and pathological events in biology. Metal coordination chemistry, especially …

It is now well established that nitric oxide (aka nitrogen monoxide) plays fundamental roles
in biochemical processes. 1, 2 Early concerns with the biology of NO were largely focused …

An axiom of hemoprotein biochemistry is that mo-lecular structure provides the basis for an
understand-ing of how these proteins work. Chemical curiosity is aroused by the …

The diverse physiological actions of the “biologic gases,” O2, CO, NO, and H2S, have
attracted much interest. Initially viewed as toxic substances, CO, NO, and H2S play important …

Abstract Information pertaining to the stereochemistry of metalloporphyrins and other
tetrapyrroles continues to expand. The present article reviews important developments of …

We have performed density functional theory (DFT) calculations of iron− porphyrin (FeP) and
its complexes with O2, CO, NO, and imidazole (Im). Our fully optimized structures agree well …

The interaction of metalloporphyrins with various nitrogen oxides of the general formula NOx
is of enormous physiological importance. Nitrosyl, nitrite, and nitrate metalloporphyrin …

Examination of the role of base in the activation of our previously reported iron (II)
complexes having the general formula [Fe (CO)(Br)(PNNP)][BPh4] revealed a five …

A first DMRG/CASSCF–CASPT2 study of a series of paradigmatic {FeNO} 6,{FeNO} 7, and
{FeNO} 8 heme–nitrosyl complexes has led to substantial new insight as well as uncovered …

Resonance Raman spectra have been recorded for the ferrous heme of soluble guanylate
cyclase (sGC), the only receptor known thus far for⊙ NO. On the basis of the frequencies of …
