[https://www.uniprot.org/uniprot/THRB_BOVIN THRB_BOVIN] Thrombin, which cleaves bonds after Arg and Lys, converts fibrinogen to fibrin and activates factors V, VII, VIII, XIII, and, in complex with thrombomodulin, protein C. Functions in blood homeostasis, inflammation and wound healing (By similarity).

== Publication Abstract from PubMed ==
 +
The crystal structure of the noncovalent complex of bovine thrombin and a fibrinogen-A alpha tridecapeptide substrate analog, G17 psi, in which the scissile bond amide nitrogen of Gly-17f has been replaced by a methylene carbon, has been determined at 2.3 A resolution with an R factor of 17.1%. The geometry of the active site indicates that the crystal structure is a close model of the true Michaelis complex. The three independently determined thrombin/G17 psi complexes in the crystal asymmetric unit reveal novel interactions for the P2' and P3' residues-Pro-18f and Arg-19f, respectively-on the carboxyl-terminal side of the scissile bond and confirm previously observed interactions of the P1 (Arg-16f) through P10 (Asp-7f) positions on the amino-terminal side. The thrombin S2' binding site for Pro-18f, as observed in all three complexes, differs from that predicted by modeling studies and is notable for including two carbonyl oxygens of the thrombin main chain. Arg-19f occupies two binding sites on thrombin, S3'A and S3'B, which have dramatically different placements for the arginyl side chain and carboxyl terminus.
