Amidolytic assay of thrombin approved that the recombinant haemadin does have the antithrombin activity . its inhibition constant 通过以chromozym th为底物的凝血酶酰胺水解实验证实了其体外生物学活性：其抑制凝血酶常数为2 . 460 . 13 10
2.
The activity of the phenol biosensor was inhibited by benzoic acid through reversible competitive inhibition mechanism and the inhibition constant is 33 . 8 u . m . the inhibition was influenced by ph value of the determined solution and increased with decreasing ph 苯甲酸对该酚传感器有竞争性可逆抑制作用，抑制常数为33 . 8 m ；溶液ph对抑制作用有较大影响，抑制作用随着ph的降低而逐渐增强。
