Supplementary information

Myoglobin also known as MB is a small globular protein with a molecular weight of approximately 17 kDa. It functions as an oxygen-binding protein and is expressed mainly in cardiac and skeletal muscle tissue where it facilitates oxygen storage and transport. The myoglobin protein plays an important role in maintaining the oxygen supply needed during muscular contraction and intense physical activity.
Biological function summary

Myoglobin in muscle cells acts to store oxygen which provides a rapid release when required during muscle contraction. Myoglobin serves as a monomer and does not form part of a complex. Its structure allows it to temporarily store and relay oxygen where it is most required enhancing the often abrupt demands of muscles for oxygen. The ability of myoglobin to bind oxygen and release it under hypoxic conditions is central to its biological role in vertebrates.

Pathways

The function of myoglobin in aerobic respiration in muscles involves its participation in the oxygen transport pathway. This protein closely interacts with hemoglobin to mobilize oxygen effectively to mitochondria during muscle contraction. Unlike hemoglobin myoglobin has a hyperbolic oxygen dissociation curve which allows it to provide oxygen at lower partial pressures contributing significantly to the efficient metabolism during hypoxia or intense muscular exertion.

Myoglobin plays a significant role in conditions such as rhabdomyolysis and myocardial infarction. Rhabdomyolysis a syndrome caused by muscle injury results in the release of myoglobin into the bloodstream. Myoglobin detection kits including myoglobin ELISA are essential tools for the diagnosis of these conditions. Moreover its rapid increase in plasma levels after heart muscle damage enables its use as an early marker for myocardial infarction. Myoglobin's interaction with proteins like creatine kinase provides valuable information on muscle damage and cardiac events.

General info

Function

Monomeric heme protein which primary function is to store oxygen and facilitate its diffusion within muscle tissues. Reversibly binds oxygen through a pentacoordinated heme iron and enables its timely and efficient release as needed during periods of heightened demand (PubMed : 30918256, PubMed : 34679218). Depending on the oxidative conditions of tissues and cells, and in addition to its ability to bind oxygen, it also has a nitrite reductase activity whereby it regulates the production of bioactive nitric oxide (PubMed : 32891753). Under stress conditions, like hypoxia and anoxia, it also protects cells against reactive oxygen species thanks to its pseudoperoxidase activity (PubMed : 34679218).
