Encapsulation of sugar beet phytoglobin BvPgb 1.2 and myoglobin in a lipid sponge phase system
Frontiers in Soft Matter, 2023 Globins are usually associated with oxygen carriage in vertebrates. However, plants also contain similar heme-containing proteins, called phytoglobins (Pgbs).

Murburn Concept: A Molecular Explanation for Hormetic and Idiosyncratic Dose Responses
Dose-Response, 2018 Recently, electron transfers and catalyses in a bevy of redox reactions mediated by hemeproteins were explained by murburn concept. The term “murburn” is abstracted from “ mur ed burn ing ” or “ m ild u n r estricted burn ing ” and connotes a novel “ m ...

Factors Controlling the Reactivity of Hydrogen Sulfide with Hemeproteins [PDF]
Biochemistry, 2009 Hemoglobin I (HbI) from the clam Lucina pectinata is an intriguing hemeprotein that binds and transports H(2)S to sulfide-oxidizing chemoautotrophic bacteria to maintain a symbiotic relationship and to protect the mollusk from H(2)S toxicity. Single point mutations at E7, B10, and E11 were introduced into the HbI heme pocket to define the reactivity of

Mechanism of Sulfide Binding by Ferric Hemeproteins
Inorganic Chemistry, 2018 The reaction of hydrogen sulfide (H2S) with hemeproteins is a key physiological reaction; still, its mechanism and implications are not completely understood. In this work, we propose a combination of experimental and theoretical tools to shed light on the reaction in model system microperoxidase 11 (MP11-FeIII) and myoglobin (Mb-FeIII), from the ...

Hydrogen sulfide activation in hemeproteins: The sulfheme scenario [PDF]
Journal of Inorganic Biochemistry, 2014 Traditionally known as a toxic gas, hydrogen sulfide (H2S) is now recognized as an important biological molecule involved in numerous physiological functions. Like nitric oxide (NO) and carbon monoxide (CO), H2S is produced endogenously in tissues and cells and can modulate biological processes by acting on target proteins.
