The Peroxidase-like Activity of the Hemoglobin-Haptoglobin Complex

The peroxidase-like activity of the hemoglobin-haptoglobin complex.

Interaction between hemoglobin subunits in the hemoglobin . haptoglobin complex.

The accessibility of hemoglobin sulfhydryl groups to modification by p-mercuribenzoate @"B) was tested in order to investigate the effect of the hemoglobinhaptoglobin association on the contact between a and /3 chain subunits. Previous evidence indicates that a molecule of tetrameric hemoglobin binds to haptoglobin as two separate a& dimers. Modification of the hemoglobin a and B chain sullhydr...

Molecular Modeling of the Human Hemoglobin-Haptoglobin Complex Sheds Light on the Protective Mechanisms of Haptoglobin

Hemoglobin (Hb) plays a critical role in human physiological function by transporting O2. Hb is safe and inert within the confinement of the red blood cell but becomes reactive and toxic upon hemolysis. Haptoglobin (Hp) is an acute-phase serum protein that scavenges Hb and the resulting Hb-Hp complex is subjected to CD163-mediated endocytosis by macrophages. The interaction between Hb and Hp is...

Clearance kinetics of haptoglobin-hemoglobin complex in the human.

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
