Gene name: ralA    Texpresso search in the literature
Synonym(s): RalA, RalA antitoxin of the RalRA toxin-antitoxin system
Genome position: 1413556 --> 1413734
Strand: forward
Sequence: Get ribonucleotide sequence FastaFormat
GC content %:  
36.87
Note(s): RalA acts as the antitoxin of a type I toxin-antitoxin system with RalR. RalA RNA base-pairs with the RalR mRNA, which may prevent translation of the RalR toxin. Antitoxin activity of RalA is dependent on |FRAME: CPLX0-1461 Hfq|, and Hfq binds directly to RalA Guo Y,2014.
In wild type cells, transcript levels of ralA are undetectable Guo Y,2014.
