| Abstract: | EmpA is an extracellular metalloprotease secreted by Vibrio anguillarum.For better understanding its role in the patho-genicity of V.anguillarum strain M3,empA insertion mutant was constructed.In the mutant it decreased in extracellular proteolytic activity,swarming motility,hemolytic activity and virulence on turbot(Scophthalmus maximus).Significant decline(by 5-fold)of extracellular proteolytic activity and similar growth curve between mutant and wild type strains indicated that EmpA was the major extrace... |
