Ferritin h and l subunits structure

WebThe electrophoretically fast ferritin showed immunological identity with the slow component, but on electrophoresis in SDS it gave a peptide of 17.3 kDa, in contrast with the electrophoretically slow ferritin, which gave a major band corresponding to the L-subunit (20.7 kDa). Thus the electrophoretically fast ferritin resembles that reported by ... WebSep 2, 2010 · Ferritin in mammals is a mostly intracellular, cytosolic iron storage and detoxification protein. It consists of H- and L-subunits that assemble into a 24-subunit hollow sphere in which iron is sequestered. 1 However, ferritin can also be detected extracellularly, in cerebrospinal fluid and sinovial fluid. In serum it is an extracellular …

WebFerritin stores iron as ferrihydrite inside a shell composed of H and L protein chains. H chains contain ferroxidase centres catalysing Fe2+ oxidation, while L chains lack these centres but seem to promote ferrihydrite nucleation. Mossbauer spectroscopic studies of recombinant H-chain ferritins show the following: (1) fast Fe2+ oxidation is associated … WebFerritin concentrates cellular iron and protects cells from its toxic effects. Storage iron is sequestered in a hollow sphere composed of 24 ferritin subunits (7). There are two distinct subunits of ferritin: the H subunit of 21,000 MW and the L subunit of 19,000 MW (8). The primary sequences for H and L subunits share 55% identity but adopt ... lynyrd skynyrd gold and platinum vinyl https://shinestoreofficial.com
