House fly cytochrome b5 exhibits kinetically trapped hemin and selectivity in hemin binding

Biochemical and Biophysical Research Communications, 2003
We report that cytochrome b(5) (cyt b(5)) from Musca domestica (house fly) is more thermally stable than all other microsomal (Mc) cytochromes b(5) that have been examined to date. It also exhibits a much higher barrier to equilibration of the two isomeric forms of the protein, which differ by a 180 degrees rotation about the alpha-gamma-meso axis of ...

Hemin-Stimulated Docking of Cytochrome c to a Hemin−DNA Aptamer Complex

Biochemistry, 2002
DNA aptamers were selected for their ability to bind simultaneously to the protein cytochrome c and to the metalloporphyrin hemin. Such aptamers each contained a conserved guanine-rich core, analogous to sequences shown previously to form a hemin-binding site when folded. The detailed study of CH6A, a deletion mutant of one clone, indicated that in the

Effects of Hemin on Erythropoiesis

1989
It is clear that in vitro hemin increases the number of blood BFU-E derived colonies from normal donors. This occurs with sickle donors as well, despite the increased levels of hemin in vivo in these patients. The effect of hemin on relative gamma globin synthesis is inconsistent, however.

Increased antioxidative capacity and decreased cadmium uptake contribute to hemin-induced alleviation of cadmium toxicity in Chinese cabbage seedlings.

Ecotoxicology and Environmental Safety, 2019
Hemin (ferroprotoporphyrin IX), a compound derivative of heme, has been shown to exert numerous beneficial physiological functions in the resistance of plant to various abiotic stresses.

Target-inspired Pb2+-dependent DNAzyme for ultrasensitive electrochemical sensor based on MoS2-AuPt nanocomposites and hemin/G-quadruplex DNAzyme as signal amplifier.

Biosensors & bioelectronics, 2019
In this work, a novel Pb2+ electrochemical DNAzyme sensor was developed for ultrasensitive detection of lead ions (Pb2+) in water environment by coupling with the MoS2-AuPt nanomaterials and hemin/G-quadruplex DNAzyme, which acting as the ...

Nickel metal-organic framework nanosheet/hemin composite as biomimetic peroxidase for electrocatalytic reduction of H2O2

Journal of Electroanalytical Chemistry, 2019
A facile and efficient synthesis of hemin containing metal–organic framework (MOF) nanocomposite was reported. Two dimensional (2D) Ni–MOF nanosheets have been used as a new type of matrix material to immobilize hemin. Scanning electron microscopy (SEM),

Competitive electrochemical immunosensor for maduramicin detection by multiple signal amplification strategy via hemin@Fe-MIL-88NH2/AuPt.

Biosensors & bioelectronics, 2019
Maduramicin (MD) is a type of monoglycoside polyether ionophore antibiotic that can effectively treat coccidiosis and facilitate animal growth. However, its extensive and excessive use brings potential risk to human health.
