RECOMBINANT HUMAN CELLULAR COAGULATION FACTOR XIII
Structural highlights
DiseaseF13A_HUMAN Defects in F13A1 are the cause of factor XIII subunit A deficiency (FA13AD) [MIM:613225. FA13AD is an autosomal recessive disorder characterized by a life-long bleeding tendency, impaired wound healing and spontaneous abortion in affected women.[1] FunctionF13A_HUMAN Factor XIII is activated by thrombin and calcium ion to a transglutaminase that catalyzes the formation of gamma-glutamyl-epsilon-lysine cross-links between fibrin chains, thus stabilizing the fibrin clot. Also cross-link alpha-2-plasmin inhibitor, or fibronectin, to the alpha chains of fibrin. Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMedThe structure of recombinant human cellular factor XIII zymogen was solved in its monoclinic crystal form and refined to an R-factor of 18.3% (Rfree = 23.6%) for all data between 40.0 and 2.1 A resolution. Two non-proline cis peptide bonds were detected. One is between Arg310 and Tyr311 close to the active site cysteine residue (Cys314) and the other is between Gln425 and Phe426 at the dimerization interface. The structure and the role of these cis peptides are discussed in the light of their possible importance for factor XIII function. Two non-proline cis peptide bonds may be important for factor XIII function.,Weiss MS, Metzner HJ, Hilgenfeld R FEBS Lett. 1998 Feb 27;423(3):291-6.
