title: [Binding of K 1-3 and K 4 fragments of plasminogen containing lysine-binding sites with fibrinogen and its fragments].
abstract: Interaction of plasminogen K 1-3 and K 4 fragments containing lysine binding sites with fibrinogen and its fragments has been investigated. It has been established that K 1-3 fragment binds to fibrinogen and its E and DL fragments. K 4 fragment does not bind to E and DL fragments, but it interacts with fibrinogen. K 4 fragment does not interact with early fibrinogen proteolysis X2 fragment which differs from the native molecule of fibrinogen in the alpha C domain absence. The results obtained indicate that lysine binding sites located at plasminogen K 1-3 and K 4 fragments correspond to different fibrinogen molecule centres. The centre complementary to K 4 fragment lysine binding sites could be located at the fibrinogen alpha C domain.
