Erwinia carotovora DsbA mutants: evidence for a periplasmic-stress signal transduction system affecting transcription of genes encoding secreted proteins.

The dsbA genes, which encode major periplasmic disulfide-bond-forming proteins, were isolated from Erwinia carotovora subsp. carotovora (Ecc) and Erwinia carotovora subsp. atroseptica (Eca), and the dsbC gene, encoding another periplasmic disulfide oxidoreductase was isolated from Ecc.

The general secretion pathway of Erwinia carotovora subsp. carotovora: analysis of the membrane topology of OutC and OutF.

The out gene cluster of Erwinia carotovora subsp. carotovora (Ecc) encodes the proteins of the type II or general secretory pathway (GSP) apparatus which is required for secretion of pectinase and cellulase. In this study, fusions between Ecc out genes and the topology probe blaM were constructed.
