Protein

Transcriptional regulator SlyA

Gene

slyA

Organism
Salmonella typhimurium (strain LT2 / SGSC1412 / ATCC 700720)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Transcription regulator that can specifically activate or repress expression of target genes. Required for virulence and survival in the macrophage environment. Probably activates expression of ispA, xseB genes, and of omp operon.2 PublicationsUniRule annotation
