WebThe study of the direct regulon of AmrZ and the phenotypic analyses of an amrZ mutant in Pseudomonas ogarae F113 has shown that this protein plays a crucial role in the regulation of several cellular functions, including motility, biofilm formation, iron homeostasis, and bis-(3′-5′)-cyclic dimeric guanosine monophosphate (c-di-GMP) turnover ... Web2 days ago · In mammals, the cytosolic iron storage protein ferritin plays a central role in maintaining iron homeostasis (8). Ferritin forms cages comprising 24 light (FTL) and heavy (FTH) subunits, and can store up to some 3000 ferric iron (Fe 3+) ions (9). In iron-deficient conditions, the production of ferritin is suppressed at the post-transcriptional ...
