CC -!- FUNCTION: Effector proteins function to alter host cell physiology and
CC promote bacterial survival in host tissues. This protein is an E3
CC ubiquitin ligase that interferes with host's ubiquitination pathway (By
CC similarity). Required for inducing polymorphonuclear leukocytes
CC migration across the intestinal epithelium.
CC {ECO:0000250|UniProtKB:Q8ZNR3, ECO:0000269|PubMed:11207586}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=S-ubiquitinyl-[E2 ubiquitin-conjugating enzyme]-L-cysteine +
CC [acceptor protein]-L-lysine = [E2 ubiquitin-conjugating enzyme]-L-
CC cysteine + N(6)-ubiquitinyl-[acceptor protein]-L-lysine.;
CC EC=2.3.2.26;
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:11207586}. Host
CC mitochondrion {ECO:0000269|PubMed:15866946}. Note=Secreted via type III
CC secretion system 1 (SPI-1 TTSS), and delivered into the host cell via a
CC Sip-dependent pathway. Localizes to the mitochondria of host cell.
CC {ECO:0000269|PubMed:15866946}.
CC -!- DOMAIN: Amino acids 100 to 347 are sufficient to target SopA to the
CC mitochondria. {ECO:0000269|PubMed:15866946}.
CC -!- PTM: Ubiquitinated in the presence of host E1 ubiquitin-activating
CC enzyme, E2 ubiquitin-conjugating enzyme and ubiquitin.
CC {ECO:0000250|UniProtKB:Q8ZNR3}.
CC -!- DISRUPTION PHENOTYPE: Mutants are significantly less enteropathogenic
CC that the wild-type strain in intestinal ligated loops and are impaired
CC in their ability to promote polymorphonuclear leukocytes movements
CC across the model epithelial monolayer. {ECO:0000269|PubMed:11207586}.
CC -!- SIMILARITY: Belongs to the SopA E3 ligase family. {ECO:0000305}.
