Preliminary studies of biosynthesis of heme O and heme A in intraerythrocytic stages of P. falciparum
(BioMed Central, 2014-09)
Intermediates of the isoprenoid metabolism can bind to heme groups. Heme is critical and its derivatives, heme O and heme A, are the main compounds of aerobic respiration. They are synthesized by farnesylation of heme ...
Non-heme iron as ferrous sulfate does not interact with heme iron absorption in humans
(2012)
The absorption of heme iron has been described as distinctly different from that of non-heme iron. Moreover, whether heme and non-heme iron compete for absorption has not been well established. Our objective was to investigate ...
Heme oxygenase 1 overexpression increases iron fluxes in Caco-2 cells

HmuS and HmuQ of Ensifer/Sinorhizobium meliloti degrade heme in vitro and participate in heme metabolism in vivo
(Springer, 2016-04)
Ensifer meliloti is a nitrogen-fixing symbiont of the alfalfa legume able to use heme as an iron source. The transport mechanism involved in heme acquisition in E. meliloti has been identified and characterized, but the ...
Heme carrier protein 1 transports heme and is involved in heme-fe metabolism
(AMER PHYSIOLOGICAL SOC, 2012)
Desaturation and heme elevation during COVID-19 infection: a potential prognostic factor of heme oxygenase-1
Increased heme levels, anemia, and desaturation occur during infection. We aimed to
compare the levels of heme, heme oxygenase-1 (HO-1), ferritin, and bilirubin in coronavirus
disease 2019 (COVID-19) patients at different ...
Heme-iron utilization by Leptospira interrogans requires a heme oxygenase and a plastidic-type ferredoxin-NADP+ reductase
(Elsevier Science, 2014-07)
Background: Heme oxygenase catalyzes the conversion of heme to iron, carbon monoxide and biliverdin employing oxygen and reducing equivalents. This enzyme is essential for heme-iron utilization and contributes to virulence ...
The effect of proteins from animal source foods on heme iron bioavailability in humans
(Elsevier, 2016)
Forty-five women (35-45 year) were randomly assigned to three iron (Fe) absorption sub-studies, which measured the effects of dietary animal proteins on the absorption of heme Fe. Study 1 was focused on heme, red blood ...
