[[https://www.uniprot.org/uniprot/IPA3_SHIFL IPA3_SHIFL]] 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. Synthesizes a 'Lys-48'-linked ubiquitin chain, which requires non-covalent binding between ubiquitin and the host ubiquitin-conjugating enzyme UBE2D1.<ref>PMID:18997779</ref>

== Publication Abstract from PubMed ==
 +
Bacterial pathogens have evolved effector proteins with ubiquitin E3 ligase activities through structural mimicking. Here we report the crystal structure of the Shigella flexneri type III effector IpaH3, a member of the leucine-rich repeat (LRR)-containing bacterial E3 family. The LRR domain is structurally similar to Yersinia pestis YopM and potentially binds to substrates. The structure of the C-terminal E3 domain differs from the typical RING- and HECT-type E3s. IpaH3 synthesizes a Lys48-linked ubiquitin chain, and the reaction requires noncovalent binding between ubiquitin and a specific E2, UbcH5. Free ubiquitin serves as an acceptor for IpaH3-catalyzed ubiquitin transfer. Cys363 within a conserved CXD motif acts as a nucleophile to catalyze ubiquitin transfer through a transthiolation reaction. The D365N mutant is devoid of E3 activities but turns into a potent ubiquitin-E2 thioesterase. Our analysis establishes a structurally and mechanistically distinct class of ubiquitin ligases found exclusively in pathogenic or symbiotic bacteria.
