Categories containing this gene/protein

protein secretion, membrane proteins

This gene is a member of the following regulons

The gene

Basic information

  • Locus tag: BSU19040

Phenotypes of a mutant

From unsuccessful trials to knock out the gene it was concluded that csaA apparently is essential. However, in a conditional mutant (Pspac-csaA), depletion of the gene product is not lethal. But secretion of some proteins including SdpC was reported to be affected unter such conditions.PubMed
