Protein
E3 ubiquitin-protein ligase SlrP
Organism
Salmonella typhimurium (strain LT2 / SGSC1412 / ATCC 700720)
Function
Effector proteins function to alter host cell physiology and promote bacterial survival in host tissues. This protein is an E3 ubiquitin ligase that interferes with host's ubiquitination pathway. Can ubiquitinate both ubiquitin and host TXN (thioredoxin). Leads to significant decrease of thioredoxin activity and increase of host cell death.
Similarity
Belongs to the LRR-containing bacterial E3 ligase family.
