WebIn vitro, recombinant AHSP promoted folding of newly translated alpha-globin, enhanced its refolding after denaturation, and facilitated its incorporation into HbA. Moreover, in erythroid precursors, newly formed free alpha-globin was destabilized by loss of AHSP. Therefore, in addition to its previously defined role in detoxification of excess ... WebEach protein chain arranges into a set of alpha-helix structural segments connected together in a globin fold arrangement. Such a name is given because this arrangement is the same folding motif used in other …

WebMar 5, 2009 · AHSP binds nascent apo α globin, facilitates its folding, and promotes its incorporation into hemoglobin A (HbA). During β globin deficiency, exposure to ROS or hypoxia, AHSP generates a more stable “bis-histidyl” form of α globin in which the heme iron is oxidized and liganded by 2 histidines within the globin polypeptide . The biologic ... The globins are a superfamily of heme-containing globular proteins, involved in binding and/or transporting oxygen. These proteins all incorporate the globin fold, a series of eight alpha helical segments. Two prominent members include myoglobin and hemoglobin. Both of these proteins reversibly bind oxygen … See more Globin superfamily members share a common three-dimensional fold. This 'globin fold' typically consists of eight alpha helices, although some proteins have additional helix extensions at their termini. Since the globin … See more Globins evolved from a common ancestor and can be divided into three lineages: • Family M (for myoglobin-like) or F (for FHb-like), which has a typical 3/3 fold. • Family S (for sensor-like), again with a 3/3 fold. See more The globin fold (cd01067) also includes some non-haem proteins.
