Fig. 4From: The proteolytic activity of Listeria monocytogenes HtrAInhibition of LmHtrA. 2 μg of recombinant LmHtrA were incubated with 10 μg casein and increasing concentrations (1–50 μM) of a small molecular HtrA inhibitor. The relative amount of β-casein was quantified by densitometry from three independent experiments. These results are given as arbitrary units with β-casein levels which were treated with 50 μM inhibitor set to 100%. Asterisks (*) label casein cleavage productsBack to article page
