[Microcalorimetric studies of temperature transitions in fibrinogen and its proteolytic fragments].
Melting of fibrinogen and its proteolytic fragments has been studied by differential scanning microcalorimetry. It has been shown that the fibrinogen molecule contains at least nine cooperative regions. One of them pertains to the central structural block (domain E), two of them are formed by the structures removed at proteolytic fragmentation and the others make part of the terminal structural blocks (domains D). A scheme of localization of melting regions in the fibrinogen molecule is proposed on the basis of the results obtained.
