The rhizobacterium Pseudomonas brassicacearum forms phenotypic variants which do not show extracellular protease and lipase activity. The operon encoding these enzymes, a serine protease homolog, and a type I secretion machinery was characterized. Transcriptional lacZ gene fusions revealed that the expression of the operon is under the control of phase variation.
