5). Expression of the dpp operon (pML3757; Supplementary Table 3) increased growth of Mtb with heme and hemoglobin as iron sources in the presence of tryptone-derived peptides (Supplementary Fig. 5). Collectively, these results indicate that peptides can interfere with heme uptake by the Mtb...
This behavior has been first described in bacteria for the hmuO gene, a member of the DtxR regulon that is required for the utilization of heme and hemoglobin as iron sources by Corynebacterium diphteriae C7 [42]. In this case, expression studies with a hmuO-lacZ fusion construct in a ...
Iron-binding proteins and heme compounds as iron sources for Vibrio anguillarum. Curr. Microbiol. 23:221-226.Mazoy, R. and Lemos, M.L. (1991) Iron-binding proteins and heme compounds as iron sources for Vibrio anguillarum. Curr. Microbiol. 135, 221-226....
Heme compounds as iron sources for nonpathogenic Rhibozium bacteria.Examines the use of heme compounds as iron sources for nonpathogenic Rhibozium bacteria. Indications that the use of hemoglobin as iron source is not restricted to animal-pathogenic microorganisms; Study of the use of hemin, ...

この技術は、[4- 14 C] 5-アミノレブリン酸([14 C] 5-ALA)、哺乳動物細胞においてヘム合成のレベルを測定するためのヘム生合成経路における早期の前駆体の1つを使用します。このアッセイは、[14 C]ヘムおよびヘムに取り込まれた放射能の測定を抽出した5-ALAとの細胞のインキュベーショ...
These data illustrate that heme-bound iron is a source of iron similar to lactoferrin. This work extends our findings about the multiple sources of iron for regulating virulence genes of T. vaginalis. 展开 关键词: Hemoglobin Hemin Host-parasite Iron Regulation Trichomonas vaginalis Vaginal ...
Simpler iron species originating from degradation of heme proteins and other sources bind to negatively charged phospholipids in membranes and catalyze the cleavage of preformed lipid hydroperoxides. Heme initiated lipid peroxidation, involved in pathogenesis in humans, is autocatalytic and forms lipid ...
Hemoglobin regeneration efficiency (HRE) and apparent iron absorption were consistently higher in anemic rats and were inversely related to iron intake. No more than two-thirds of iron from all the iron sources was absorbed. 59Fe was high in the blood of anemic rats and continued to increase ...
