The specific proteolytic activation steps of blood coagulation are catalyzed by serine proteinases that are homologous to each other and to the archetypal serine proteinases

Public Health Relevance

The formation of a blood clot results from a series of very specific activation steps in which an inactive precursor in blood is cleaved at specific sites to form an active product. Our research is directed towards obtaining new insights into how these reactions of high specificity occur. The findings will reveal novel strategies for interfering with these reactions and for the treatment of life-threatening blood clots associated with a variety of human diseases
