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 …

Protein design is a valuable tool for understanding the fundamental factors that dictate
protein structure and function. The field of protein design has seen significant progress over …

Since their discovery in the 1960s, cytochrome P450-dependent monooxygenases have
very much attracted the interest of chemists because of their ability to catalyze the selective …

This review summarizes recent developments in the investigation of the electronic
structures, spectroscopic properties, and reactivities of ferrous and ferric heme-nitrosyls and …

The gaseous XO molecules (X= C, N or O) bind to the heme prosthetic group of heme
proteins, and thereby activate or inhibit key biological processes. These events depend on …

The coordination chemistry of the one-electron reduced form of nitric oxide, termed a nitroxyl
or nitrosyl hydride (NO− or HNO), is described with special focus on its interaction with …

Nitrite is an important species in the global nitrogen cycle, and the nitrite reductase enzymes
convert nitrite to nitric oxide (NO). Recently, it has been shown that hemoglobin and …

We present the structures of bovine catalase in its native form and complexed with ammonia
and nitric oxide, obtained by X-ray crystallography. Using the NO generator 1-(N, N …

The use of multiple-scattering analysis of X-ray absorption fine structure (XAFS) data for the
determination of three-dimensional structures of the active sites of proteins and reactive …

DFT calculations in our laboratory and elsewhere have elucidated fundamental aspects of
the structure and bonding of a variety of metalloporphyrin− diatomic complexes, including …
