摘要:... We have shown in our previous studies that hydrogen peroxide formed in association with hemoglobin autoxidation reacts with hemoglobin and initiates a cascade of reactions that results in heme degradation with the formation of two fluorescent emission bands and the release ...

摘要:Abstract(#br)As part of the machinery to acquire, internalize and utilize heme as a source of iron from the host, some bacteria possess a canonical heme oxygenase, where heme plays the dual role of substrate and cofactor, the later catalyzing the cleavage of the heme moiety us...

摘要:Background & Aims(#br)Biliverdin and bilirubin were previously considered end products of heme catabolism; now, however, there is evidence for further degradation to diverse bioactive products. Z -BOX A and Z -BOX B arise upon oxidation with unknown implications for hepatocell...

摘要:Abstract(#br)HutZ from Vibrio cholerae is a dimeric enzyme that catalyzes degradation of heme. The highly conserved Arg92 residue in the HutZ family is proposed to interact with an iron-bound water molecule in the distal heme pocket. To clarify the specific role of Arg92 in the heme degradation...

摘要:Abstract(#br)Two fluorescent heme degradation compounds are detected during autoxidation of oxyhemoglobin. These fluorescent compounds are similar to fluorescent compounds formed when hydrogen peroxide reacts with hemoglobin [E. Nagababu and J. M. Rifkind, Biochem. Biophys. ...

摘要:... UV–vis, fluorescence and FT-IR spectroscopies were used to study the whole conformational changes and partial degradation of heme. Hb species calculated using Benesch equations indicated that the concentration of oxy-Hb was decreased from 9.97 μM to 6.56 μM, while the ...

摘要:... Nevertheless, RBC oxidant stress has been demonstrated by the formation of a fluorescent heme degradation product (excitation (ex) 321 nm, emission (em) 465 nm) both in vitro and in vivo. We investigated the possibility that the observed heme degradation results from ROS gene...

摘要:Abstract(#br)Heme degradation through the action of heme oxygenase (HO) is unusual in that it utilizes heme as both a substrate and cofactor for its own degradation. HO catalyzes the oxygen-dependent degradation of heme to biliverdin with the release of CO and “free” iron. ...

摘要:Abstract(#br)In this study the hemoglobin heme degradation upon interaction with sodium dodecyl sulfate (SDS) was investigated using UV–vis and fluorescence spectroscopy, multivariate curve resolution analysis, and chemiluminescence method. Our results showed that heme degradation...

摘要:... In this state, glucose autoxidation, ketoamine, and oxidative advance glycation end products (AGEs) formation are considered as major sources of ROS and perhaps heme degradation during hemoglobin glycation. However, whether fructose mediated glycation produces ROS and heme degradation...
