Background Myoglobin (Mb) and neuroglobin (Ngb) are representative members of pentacoordinated and bis-histidyl, hexacoordinated globins. In spite of their low sequence identity, they show surprisingly similar three-dimensional ...

Azanone (HNO, nitroxyl) is a highly reactive molecule that, in the past few years, has drawn significant interest because of its pharmacological properties. However, the understanding of how, when, and where endogenous HNO ...

The objective of this preliminary study was to determine the optimum concentration of antioxidants in the soluble fractions of Maillard Reaction Products (MRPs similar) (formed by sarcoplasmic proteins of beef and ...

The influence of pressure on the equilibrium between five-(5c) and six-coordination (6c) forms in neuroglobin (Ngb) and myoglobin (Mb) has been examined by means of molecular dynamics (MD) simulations at normal and high ...

This chapter reviews the application of classical and quantum-mechanical atomistic simulation tools used in the investigation of several relevant issues in nitric oxide reactivity with globins and presents different ...

The Antarctic icefish Chaenocephalus aceratus lacks the globins common to most vertebrates, hemoglobin and myoglobin, but has retained neuroglobin in the brain. This conserved globin has been cloned, over-expressed and ...

A new family of compounds is presented as potential carbon monoxide releasing molecules (CORMs). These compounds, based on tetrachlorocarbonyliridate (III) derivatives, were synthesized and fully characterized by X-ray ...

Para el consumidor de carne vacuna la calidad sensorial es importante al momento de la compra y el consumo. El color depende mayormente de la concentración de mioglobina y el pH, en tanto que la terneza está relacionada ...
