==Overview==
{{ABSTRACT_11601975}}
The crystal structure of native chicken fibrinogen (320 kDa) complexed with two synthetic peptides has been determined at a resolution of 2.7 A. The structure provides the first atomic-resolution view of the polypeptide chain arrangement in the central domain where the two halves of the molecule are joined, as well as of a putative thrombin-binding site. The amino-terminal segments of the alpha and beta chains, including fibrinopeptides A and B, are not visible in electron density maps, however, and must be highly disordered. The alphaC domain is also very disordered. A residue by residue analysis of the coiled coils with regard to temperature factor shows a strong correlation between mobility and plasmin attack sites. It is concluded that structural flexibility is an inherent feature of fibrinogen that plays a key role in both its conversion to fibrin and its subsequent destruction by plasmin.
