CC -!- FUNCTION: Part of the AaxABC system, catalyzes the decarboxylation of
CC L-arginine. The arginine uptake by the bacterium in the macrophage may
CC be a virulence factor against the host innate immune response (By
CC similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H(+) + L-arginine = agmatine + CO2; Xref=Rhea:RHEA:17641,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:16526, ChEBI:CHEBI:32682,
CC ChEBI:CHEBI:58145; EC=4.1.1.19;
CC -!- COFACTOR:
CC Name=pyruvate; Xref=ChEBI:CHEBI:15361; Evidence={ECO:0000250};
CC Note=Binds 1 pyruvoyl group covalently per subunit. {ECO:0000250};
CC -!- SUBUNIT: Trimer of an alpha-beta dimer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the pyruvoyl-dependent arginine decarboxylase
CC family. {ECO:0000305}.
