Fig. 2From: HtrA-mediated E-cadherin cleavage is limited to DegP and DegQ homologs expressed by gram-negative pathogensActive proteases expressed by pathogens. H. pylori (Hp), EPEC (Ep), S. Typhimurium (St), Y. enterocolitica (Ye) and P. mirabilis (Pm) were sonicated and protein lysates were analyzed by casein zymography (upper panel). As a control, proteins were separated by SDS PAGE followed by coomassie staining to show equal protein loading (lower panel)Back to article page
