ZapA, the IgA-degrading metalloprotease of Proteus mirabilis, is a virulence factor expressed specifically in swarmer cells.

Molecular microbiology - 1 May 1999

Abstract excerpt

The IgA-degrading metalloprotease, ZapA, of the urinary tract pathogen Proteus mirabilis is co-ordinately expressed along with other proteins and virulence factors during swarmer cell differentiation. In this communication, we have used zapA to monitor IgA protease expression during the differentiation of vegetative swimmer cells to fully differentiated swarmer cells. Northern blot analysis of wild-type cells and...
