LT2. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: X-ray diffraction, Resolution 2.394Å Ligands: EDO Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function SSEL_SALTY Effector proteins function to alter host cell physiology and promote bacterial survival in host tissues. This protease targets the host cell ubiquitin pathway by acting as a deubiquitinase in infected host cells. Specifically hydrolyzes mono- and polyubiquitin substrates in vitro with a preference for 'Lys-63'-linked ubiquitin chains, suggesting that it interferes with a signaling pathway rather than inhibiting proteasomal-dependent degradation of its targets. Does not possess desumoylating activity. Is required for the Salmonella-induced delayed cytotoxicity in macrophages and full virulence. Is not required for intracellular bacterial replication.
