Structural and functional role of the beta-strand insert (gamma 381-390) in the fibrinogen gamma-module. A "pull out" hypothesis.
Study of the folding status of the fibrinogen gamma-module (residues gamma 148-411) revealed that its COOH-terminal beta-strand (residues gamma 381-390), that is normally inserted into its central domain, can be removed without destroying its compact structure. Based on this and other observations we propose a "pull out" hypothesis that suggests a mechanism for the formation of transverse gamma-gamma crosslinks in fibrin.
