Crystal structure of rat heme oxygenase-1 in complex with heme [PDF]
Heme oxygenase catalyzes the oxidative cleavage of protoheme to biliverdin, the first step of heme metabolism utilizing O2 and NADPH. We determined the crystal structures of rat heme oxygenase‐1 (HO‐1)–heme and selenomethionyl HO‐1–heme complexes. Heme is sandwiched between two helices with the δ‐meso edge of the heme being exposed to the surface ...

Immunolocalization of heme oxygenase-1 in periodontal diseases
Context: Chronic periodontitis is an inflammatory condition of supporting tissues initiated by organisms in dental plaque. The reactive oxygen species and free radicals mediate connective tissue destruction in periodontitis.

How Heme Oxygenase-1 Prevents Heme-Induced Cell Death. [PDF]
Earlier observations indicate that free heme is selectively toxic to cells lacking heme oxygenase-1 (HO-1) but how this enzyme prevents heme toxicity remains unexplained.

Heme oxygenase-1, oxidation, inflammation and atherosclerosis [PDF]
Atherosclerosis is an inflammatory process of the vascular wall characterized by the infiltration of lipids and inflammatory cells. Oxidative modifications of infiltrating low density lipoproteins and induction of oxidative stress play a major role in ...

Heme oxygenase 1 overexpression increases iron fluxes in Caco-2 cells [PDF]
Heme oxygenase-1 is a microsomal enzyme that, when induced by stress, protects the cells from oxidative injury. Heme oxygenase-1 participates in the cleavage of the heme ring producing biliverdin, CO and ferrous Fe.
