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         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       T3SS), 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}.
