Differences in cattle globins [PDF]
Biochemical Journal, 1965 1. Comparisons have been made between electrophoretic mobilities of the cattle haemoglobins, HbA, HbB, HbC, HbD and HbF, at pH8.9. The fastest was HbB, then came in decreasing order HbF, HbC, HbA and HbD. 2. Globins were prepared from the main fractions of the five haemoglobins by CM-cellulose chromatography and investigated by starch-gel ...

New Water Oxidation Mechanism in Photosystem II Resolves Major Experimental Controversies
Angewandte Chemie, EarlyView.In Photosystem II Oxygen Evolving Complex, we discovered the O3‐O6 peroxide at lower energy. Assignment of the O3 ligated by histidine (His337) as a slow exchanging substrate and its coupling with O6 give the O─O bond formation mechanism most consistent with all currently available experimental data. Proposal shows how protein environment can steer the

Electron transfer function versus oxygen delivery: a comparative study for several hexacoordinated globins across the animal kingdom. [PDF]
PLoS ONE, 2011 Caenorhabditis elegans globin GLB-26 (expressed from gene T22C1.2) has been studied in comparison with human neuroglobin (Ngb) and cytoglobin (Cygb) for its electron transfer properties. GLB-26 exhibits no reversible binding for O(2) and a relatively low

Human globin ψB2is not a globin-related sequence [PDF]
Nucleic Acids Research, 1982 We have determined the complete nucleotide sequence of 3.4 kilobase pairs of DNA covering the region of the human beta globin gene cluster where a human globin-related sequence psi beta 2 was thought to lie (Fritsch, Lawn, and Maniatis (1980) Cell 19, 959-972).

Hemoglobin switching in mice carrying the Klf1Nan variant
Haematologica, 2020 Haploinsufficiency for transcription factor KLF1 causes a variety of human erythroid phenotypes, such as the In(Lu) blood type, increased HbA2 levels, and hereditary persistence of fetal hemoglobin. Severe dominant congenital dyserythropoietic anemia IV

More than hemoglobin – the unexpected diversity of globins in vertebrate red blood cells [PDF]
, 2022 In many multicellular organisms, oxygen is transported by respiratory proteins, which are globins in vertebrates, between respiratory organs and tissues.

Redox-Regulation of α-Globin in Vascular Physiology
Antioxidants, 2022 Interest in the structure, function, and evolutionary relations of circulating and intracellular globins dates back more than 60 years to the first determination of the three-dimensional structure of these proteins.

The Coup-TFII orphan nuclear receptor is an activator of the γ-globin gene
Haematologica, 2020 The human fetal γ-globin gene is repressed in the adult stage through complex regulatory mechanisms involving transcription factors and epigenetic modifiers.

Globin genes on the move [PDF]
Journal of Biology, 2008 Recent data published in BMC Biology from the globin gene clusters in platypus, together with data from other species, show that beta-globin genes transposed from one chromosomal location to another. This resolves some controversies about vertebrate globin gene evolution but ignites new ones.
