Figure 3From: Functional characterization of a cystatin from the tick Rhipicephalus haemaphysaloides Inhibition of protease activities by the recombinant protein of RHcyst- 1, a novel type 1 cystatin isolated from the tick Rhipicephalus haemaphysaloides . Cathepsin L, B, C, H, and S and papain were incubated with each of the substrates in the presence of different concentrations of rRHcyst-1. Incubation of cathepsins without rRHcyst-1 resulted in 100% enzyme activity.Back to article page
