'''Crystal structure of native chicken fibrinogen with two different bound ligands'''

__TOC__
==Overview==
</StructureSection>
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.
 
==About this Structure==
1M1J is a [[Protein complex]] structure of sequences from [http://en.wikipedia.org/wiki/Gallus_gallus Gallus gallus]. This structure supersedes the now removed PDB entry 1JFE. The following page contains interesting information on the relation of 1M1J with [[http://pdb.rcsb.org/pdb/static.do?p=education_discussion/molecule_of_the_month/pdb83_1.html Fibrin]]. Full crystallographic information is available from [http://oca.weizmann.ac.il/oca-bin/ocashort?id=1M1J OCA].
