Purification and characterization of two distinct metalloproteases secreted by the entonopathogenic bacterium Photorhabdus sp. strain Az29

Article Abstract:

The Photorhabdus sp. strain Az29 is biologically similar to the Azorean nematode of the genus Heterorhabditis in a complicated environment wherein the insects are subject to the virus even at low temperatures. In categorizing the studies of proteases developed by these bacteria, the distinct biochemical features and DNA series are identified for metalloproteases which are secreted by various species or by the various strains of the same species.

Regulation of Vibrio anguillarum empA metalloprotease expression and its role in virulence

Article Abstract:

The details indicated that the expression of empA is distinctly regulated in Vibrio anguillarum strains NB10 and M93Sm and it needs quorum-sensing molecules and gastrointestinal mucus. It is also assumed that the empA metalloprotease of Vibrio anguillarum is significant for virulence at the time when Atlantic salmon is infected.

Induction of protease activity in Vibrio anguillarum by gastrointestinal mucus

Article Abstract:

Gastrointestinal mucus stimulates Vibrio anguillarum to produce a metalloprotease encoded by the empA gene. This organism infects fish and crustaceans and exhibits strong chemotaxis toward gastrointestinal mucus.
