CC -!- FUNCTION: Effector proteins function to alter host cell physiology and
CC promote bacterial survival in host tissues. This protein includes
CC tyrosine phosphatase and GTPase activating protein (GAP) activities.
CC After bacterial internalization, GAP mediates the reversal of the
CC cytoskeletal changes induced by SopE. This function is independent of
CC its tyrosine phosphatase activity, which remains unclear (By
CC similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + O-phospho-L-tyrosyl-[protein] = L-tyrosyl-[protein] +
CC phosphate; Xref=Rhea:RHEA:10684, Rhea:RHEA-COMP:10136, Rhea:RHEA-
CC COMP:10137, ChEBI:CHEBI:15377, ChEBI:CHEBI:43474, ChEBI:CHEBI:46858,
CC ChEBI:CHEBI:82620; EC=3.1.3.48; Evidence={ECO:0000255|PROSITE-
CC ProRule:PRU10044};
CC -!- SUBUNIT: Forms a complex with SicP. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}. Host cytoplasm
CC {ECO:0000250}. Note=Secreted via type III secretion system 1 (SPI-1
CC TTSS), and delivered into the host cytoplasm. {ECO:0000250}.
CC -!- MISCELLANEOUS: Requires SicP as a chaperone for its stability and
CC secretion. {ECO:0000250}.
CC -!- SIMILARITY: In the N-terminal section; belongs to the YopE family.
CC {ECO:0000305}.
