My thesis was the characterization of biophysical … WebSiderophore and iron uptake Siderophoresare low-molecular-weight molecules that chelate iron with a very high and specific affinity. Many bacteria, both G+ and G−, produce and secrete siderophores to scavenge iron from the extracellular environment. Siderophore–iron complexes are transported into the cell through receptors in the membrane.
WebDoctoral Dissertation: "Kinetics of Gaseous Oxygen Absorption by Molten Iron and Some Iron Alloys" - 1977 (UMI # 7718099 - order from ProQuest) University of Detroit Mercy WebConsiderable progress has been made in characterizing and understanding mechanisms of siderophore synthesis, secretion, iron scavenging, and siderophore-delivered iron uptake and its release. The regulation of siderophore pathways reveals multilayer networks at the transcriptional and posttranscriptional levels.
WebApr 7, 2024 · These compounds are capable to form stable iron-complexes facilitating its internalization into the cell by using bacterial iron uptake pathways as gateways. 13, 14, 15 Vectorization of antibacterial agents by siderophores is a promising strategy able to increase the efficacy of drugs, especially for gram-negative pathogens. This approach has … WebDec 24, 2024 · Siderophores are usually classified by the ligands used to chelate the ferric iron. The majors groups of siderophores include the catecholates (phenolates), …
WebA family of four putative transporters (Arn1p–4p) in Saccharomyces cerevisiae is expressed under conditions of iron deprivation and is regulated by Aft1p, the major iron-dependent transcription factor in yeast. One of these, Arn3p/Sit1p, facilitates the uptake of ferrioxamine B, a siderophore of the hydroxamate class. Here we report that ARN family members …
WebMay 21, 2003 · The siderophore uptake process appears to involve endocytosis of the transporter subsequent to binding of its substrate, and translocation of iron across the endosomal membrane because defects in genes involved in endocytosis as well as blocking of endocytosis by the actin-inhibitor latrunculin A reduce uptake of siderophore-bound … how to rename sony headphonesWebApr 12, 2024 · Complete model (Model 1) Model 1 formalises the Fe uptake basing on the model devised by Sterckeman et al.
