Escherichia coli and Pseudomonas were the first ones to be tested; however, nowadays iron transport systems have been investigated in many other bacteria. 搂Iron Uptake in Bacteria with Emphasis on E. coli and Pseudomonas reviews the recent advancements in the field of iron transport systems in ...
Cells were grown in iron sufficient medium (5 µM). e-i, qRT PCR analysis show increase in transcript levels of genes involved in iron uptake (hmuP(e), foxA (f), fhup (g), rhrA (h) and fbpA (i)) when grown in iron-replete medium (30 µM) upon NCR247 treatment for...
Iron storage in bacteria. 来自 NCBI 喜欢 0 阅读量: 155 作者: SS Andrews 摘要: Iron is an essential nutrient for nearly all organisms but presents problems of toxicity, poor solubility and low availability. These problems are alleviated through the use of iron-storage proteins. Bacteria possess ...
the uptake of which was promoted by pentanoate, a microbiota-produced short-chain fatty acid (SCFA). Decreased cellular iron levels in regulatory T cells via the specific depletion of Transferrin receptor I (TfR1)
Siderophores selectively bind ferric iron and are involved in receptor-specific iron transport into bacteria. Several types of siderophores were synthesized, and growth-promoting or inhibitory activities when they were conjugated to carbacephalosporin, erythromycylamine, or nalidixic acid were investigated. ...
Microbial Iron Uptake 来自 Wiley 喜欢 0 阅读量: 39 作者: R Crichton 出版社: John Wiley & Sons, Ltd 摘要: Summary This chapter discusses the common principles of bacterial iron transport. It reviews siderophore iron transport across the outer membrane in Gram-negative bacteria, notably E. coli...
2.1 Biology of Iron-Metabolising Bacteria 2.1.1 Iron-Oxidising Bacteria There are a broad range of different bacteria that are capable of oxidising Fe(II) in order to obtain reducing equivalents for the generation of a PMF and reduction of NAD+. These include phototrophic organisms (R...
8. Iron Uptake inFrancisella Girija Ramakrishnan Francisella tularensisis unusual among Gram-negative bacteria in that its genome does not encode orthologs for TonB, ExbB and ExbD that typically energize the uptake of iron across the outer membrane. This organism secretes however a siderophore similar...
In the natural environments, iron availability is very limited due to extremely low solubility of ferric iron (Fe3+) under neutral pH (10−18 M)8. Bacteria thus developed various strategies to uptake iron from the environment. When intracellular levels of iron are low, bacteria turn on ...
Iron homeostasis in the macrophage is determined by uptake processes through lactoferrin, transferrin, divalent metal transporter (DMT-1), phagocytosis of senescent erythrocytes, and by export through ferroportin (Fpn1) [8]. Transferrin and its receptor (TfR1) play an important role during infection...
