Iron regulatory protein 1 (IRP1) is a redox-sensitive protein which exists in two active forms in the cytosol of eukaryotic cells. Holo-IRP1 containing a [4Fe-4S] cluster exhibits aconitase activity which catalyzes the isomerization of citrate and is

The extracytoplasmic function sigma factor AlgU of Pseudomonas aeruginosa is responsible for alginate overproduction, leading to mucoidy and chronic infections of cystic fibrosis patients. We investigated here the role of AlgU in the formation of non

Nitric oxide and peroxynitrite promote complete disruption of the [4Fe-4S] cluster of recombinant human iron regulatory protein 1

Autor: Jean-Claude Drapier, Emmanuelle Soum

Publikováno v: Journal of biological inorganic chemistry : JBIC : a publication of the Society of Biological Inorganic Chemistry. 8(1-2)

Iron regulatory protein 1 (IRP1) is a metalloprotein which regulates several proteins involved in mammalian iron homeostasis at a post-transcriptional level, by binding to specific mRNA sequences termed iron responsive elements (IREs). IRP1 exhibits
