[Complexes of the N-terminal disulfide branch point of fibrin with fibrinogen].
Investigation of fibrin N-terminal disulphide knot (N-DSK) binding with fibrinogen (F) showed, that the F-N-DSK-complex represents growing polymer structure which is soluble at early polymerization stage and forms a solid phase during the further growth. This complex is characterized by constant stoichiometry expressed by formula F (N-DSK)2. A model of the complex structure as a regular copolymer of fibrinogen and N-DSK is proposed, in which neighbouring fibrinogen molecules are clamped with two N-DSK molecules. Such copolymer was never described. Since its formation is caused by specific D-E interdomain binding, it may be considered as a peculiar analogue of fibrin polymer.
