5. Excess amount of imidazole (>50mM) and/or NaCl (>250mM) reversibly interferes
and inhibits enterokinase activity. Presence of >2M NaCl in the reaction inhibits
enterokinase completely. Enterokinase, which has 5 disulfide bridges in the structure (Lu
et al., 1999), is inhibited by the presence of reducing agents (e.g, β-mercaptoethanol).

b) Salt sensitivity: rEK is inhibited by imidazole or NaCl concentrations above 250 mM.
