Hemin-induced modifications of the antigenicity and hemin-binding capacity of Porphyromonas gingivalis lipopolysaccharide [PDF]
Previous studies have shown that the physical, biochemical, and antigenic properties of the bacterial outer membrane are profoundly influenced by the growth environment. In the present study, the effects of growth in hemin-replete (H+) and hemin-depleted (H-) media on the lipopolysaccharide (LPS) of the oral pathogen Porphyromonas gingivalis were ...

Hemin and heme-peroxidases have been considered essential catalysts for the nitrite/hydrogen peroxide (H2O2)-mediated protein nitration in vitro, understood as one of the main pathways for protein modification in biological systems. However, the role of nitric oxide (●NO) in the heme/hemin-induced protein nitration has not been studied in-depth.

Contribution of PGE2 EP1 receptor in hemin-induced neurotoxicity
Although hemin-mediated neurotoxicity has been linked to the production of free radicals and glutamate excitotoxicity, the role of the prostaglandin E2 (PGE2)-EP1 receptor remains unclear.

MolMiner: You only look once for chemical structure recognition [PDF]
Molecular structures are always depicted as 2D printed form in scientific documents like journal papers and patents. However, these 2D depictions are not machine-readable. Due to a backlog of decades and an increasing amount of these printed literature, there is a high demand for the translation of printed depictions into machine-readable formats ...

Improvement of a Hemin Standard by Recrystallization
Summary1. The purity of crude hemin preparations used, as determined by their iron content, was improved by recrystallization. 2. Crude hemin preparations in borate buffer showed variable extinction coefficients at any wavelength selected along the flat portions of the absorption spectra.

Improving the anthocyanin accumulation of hypocotyls in radish sprouts by hemin-induced NO
Background The health benefits of anthocyanins impel researchers and food producers to explorer new methods to increase anthocyanin contents in plant foods. Our previous studies revealed a positive role of nitric oxide (NO) in anthocyanin accumulation in

The Irr and RirA proteins participate in a complex regulatory circuit and act in concert to modulate bacterioferritin expression in Ensifer meliloti 1021 [PDF]
In this work we found that the bfr gene of the rhizobial species Ensifer meliloti, encoding a bacterioferritin iron storage protein, is involved in iron homeostasis and the oxidative stress response. This gene is located downstream of and overlapping the

Cj1386, an Atypical Hemin-Binding Protein, Mediates Hemin Trafficking to KatA in Campylobacter jejuni [PDF]
ABSTRACT Catalase enzymes detoxify H 2 O 2 by the dismutation of H 2 O 2 into O 2 and H 2 O through the use of hemin cofactors.

Quantitative Proteomic Analysis Reveals Changes in the Benchmark Corynebacterium pseudotuberculosis Biovar Equi Exoproteome after Passage in a Murine Host [PDF]
Corynebacterium pseudotuberculosis biovar equi is the etiologic agent of ulcerative lymphangitis. To investigate proteins that could be related to the virulence of this pathogen, we combined an experimental passage process using a murine model and high ...

Hemin-induced suicidal erythrocyte death [PDF]
Several diseases, such as malaria, sickle cell disease, and ischemia/reperfusion may cause excessive formation of hemin, which may in turn trigger hemolysis. A variety of drugs and diseases leading to hemolysis triggers suicidal erythrocyte death or eryptosis, i.e., cell membrane scrambling and cell shrinkage.
