3.4.22.14	E-64	-	559	
3.4.22.14	Fe2+	addition leads to inhibition of free actinidin whereas immobilized actinidin shows a much weaker inhibition	25	
3.4.22.14	Hg2+	-	33	
3.4.22.14	human kininogen domain 2	hybrids of chicken cystatin with human kininogen domain 2 sequences exhibit improved inhibition	100713	
3.4.22.14	iodoacetate	-	93	
3.4.22.14	KCl	minimal activity at 0.5-0.8 M, depending on substrate concentration. Minimal activity is 50-70% of the acitivity in absence of salt, with increase in KM-value and decrease in kcat-value. Slight reactivation above 0.8 M	79
