General description

Myoglobin is a heme-related, low-molecular-weight protein. It is mainly found in cardiac and skeletal muscle.

Application

Myoglobin from human heart has been used as a negative control in monitoring isoAsp formation during storage. It has also been used as an antigen in the study to identify self-antigens recognized by serum autoantibodies from unimmunized mice strains.
Myoglobin from human heart was used to study the interactions of a platinum (II) 9-aminoacridine complex with proteins and oligonucleotides by ESI-TOF MS. It was also used in the evaluation of plasma myoglobin using the Stratus CS fluorometer.

Biochem/physiol Actions

Myoglobin may help to increase diffusion and also stores O2 in oxidative muscle. It can momentarily act as an oxygen reservoir to supply oxygen when there is inadequate blood oxygen delivery at the time of intense muscular activity.

Physical form

Solution in 20 mM Tris-HCl, 1 mM EDTA and 50% glycerol, pH 8.5, 2 mg protein per mL (Lowry)

The discovery that cysteine (Cys) S-nitrosation of trout myoglobin (Mb) increases heme O2 affinity has revealed a novel allosteric effect that may promote hypoxia-induced nitric oxide (NO) delivery in the trout heart and improve myocardial efficiency. To better understand this
