Engineering tyrosine-based electron flow pathways in proteins: The case of aplysia myoglobin [PDF]

, 2012
Tyrosine residues can act as redox cofactors that provide an electron transfer ("hole-hopping") route that enhances the rate of ferryl heme iron reduction by externally added reductants, for example, ascorbate.

Mechanism Underlying Green Discolouration of Myoglobin Induced by Atmospheric Pressure Plasma

Scientific Reports, 2018
In this study, we elucidated the mechanism underlying atmospheric pressure plasma (APP)-induced green discolouration of myoglobin. Green-coloured pigments are produced upon conversion of myoglobin into sulphmyoglobin, choleglobin, verdoheme, nitrihemin ...

Metabolic Engineering of the 5‐Aminolevulinate Biosynthetic Pathway in E. coli Improves Efficiency of Hemoprotein‐Based Biocatalysis

Angewandte Chemie, EarlyView.
We have engineered the heme biosynthetic pathway in E. coli to develop an efficient cofactor supplementation system for hemoproteins. Through the incorporation of the heterogeneous C4 pathway, the engineered cells significantly increase the expression levels of active holohemoproteins and enhance the efficiency of whole‐cell and lysate‐based ...

Femtosecond X-ray emission study of the spin cross-over dynamics in haem proteins

, 2020
In haemoglobin (consisting of four globular myoglobin-like subunits), the change from the low-spin (LS) hexacoordinated haem to the high spin (HS) pentacoordinated domed form upon ligand detachment and the reverse process upon ligand binding, represent ...

Estimated glomerular filtration rate is a poor predictor of the concentration of middle molecular weight uremic solutes in chronic kidney disease [PDF]

, 2012
Background: Uremic solute concentration increases as Glomerular Filtration Rate (GFR) declines. Weak associations were demonstrated between estimated GFR (eGFR) and the concentrations of several small water-soluble and protein-bound uremic solutes ...

Myoglobin modulates the Hippo pathway to promote cardiomyocyte differentiation

iScience
Summary: The endogenous mechanisms that propagate cardiomyocyte differentiation and prevent de-differentiation remain unclear. While the expression of the heme protein myoglobin increases by over 50% during cardiomyocyte differentiation, a role for ...

Serum Myoglobin Is Associated With Postoperative Acute Kidney Injury in Stanford Type A Aortic Dissection

Frontiers in Medicine, 2022
BackgroundThe correlation between rhabdomyolysis and postoperative acute kidney injury has been reported in several surgical procedures. As a good predictor of rhabdomyolysis-related acute kidney injury, an elevated serum myoglobin level was often ...
