Hydropersulfides are reported to be good biological reductants, superior to thiols and akin to
selenols. As such, they have been previously shown to reduce metalloproteins such as ferric …

The ferrous form of sulfmyoglobin was isolated as the first stable product of the reaction of a
single mole of inorganic sulfide with 1 mole of the higher oxidation state derivative of …

Reaction of the ferric form of leghaemoglobin with hydrogen peroxide has been previously
shown to give rise to an iron (IV)-oxo (ferryl) species, and a protein radical. Inclusion of a …

Publisher Summary This chapter discusses the molecular mechanisms and methodological
aspects of the reaction of two major classes of sulfur compounds—namely, aliphatic …

1. The progress of the formation of sulphhaemoglobin from oxyhaemoglobin and sulphide
depends on the availability of oxygen. In the absence of excess oxygen, much of the …

Hemoglobin in its ferryl form oxidizes hydrogen sulfide and is transformed to
sulfhemoglobin, where the sulfur is inserted covalently at the heme edge. Shown here is …

The molecular and electronic structure of the modified prosthetic group of sulfhemoglobin
(SHb) was investigated by 1 H NMR for the low-spin ferric cyano-met and high-spin ferrous …

Protein mixed thioselenides formed by reaction of sarcoplasmic reticulum (SR) with
diselenide biradical spin labels were quantified by ESR. Whereas the reaction of SR …

• CO OH R")—(" D 70/30) and subsequent NMR analysis showed that 1 and 2 are mainly of
the threoconfiguration, the threo/erythro ratio being 88: 12 in both cases. The configuration …

Seventy years ago Hoppe-Seyler (1863) found that if a current of H2S is passed through a
solution of oxyhæmoglobin a distinct adsorption band appears in the red end of the …
