The interaction of delta (Ser50)-hirudin with alpha-thrombin has been investigated. Deletion of Ser50 of r-hirudin caused a 2.7 fold increase of the Ki for its complex with alpha-thrombin. Determination of the rate constants kon and koff for complex formation showed that this effect was mainly due to a change in koff.
已对δ（Ser50）-水蛭素与α-凝血酶的相互作用进行了研究。r-水蛭素Ser50的缺失导致其与α-凝血酶形成复合物的Ki增加了2.7倍。复合物形成的速率常数kon和koff的测定表明，这种效应主要是由于koff的变化。
