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
