Crystal Structure of the Complex Between Thrombin and the Central "E" Region of Fibrin

March 2, 2004
Author(s)
I Pechik, J Madrazo, M W. Mosesson, I Hernandez, G L. Gilliland, L Medved
Non-substrate interactions of thrombin with fibrin play an important role in modulating its procoagulant activity. To establish the structural basis for these interactions, we crystallized PPACK-inhibited thrombin in complex with a fragment, Eht
