[Manifestations of domain organization of the Staphylococcus aureus protein A during heat denaturation of its structure].
Melting of protein A from Staphylococcus aureus has been studied in neutral medium by the methods of microcalorimetry and circular dichroism. The melting process of protein A is shown to consist of, at least, 5 independent transitions. The transition with the heat absorption maximum at 38 degrees is ascribed to the melting of the C-terminal domain of protein A. The analysis of amino acid sequences has shown the existence of structural basis for differences in heat stability of the Fc-binding domains of protein A.
