Protein attributes

Sequence length	195 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Part of the AaxABC system, catalyzes the decarboxylation of L-arginine. The arginine uptake by the bacterium in the macrophage may be a virulence factor against the host innate immune response By similarity.
Catalytic activity	L-arginine = agmatine + CO2.
Cofactor	Pyruvoyl group By similarity.
Subunit structure	Trimer of an alpha-beta dimer By similarity.
Subcellular location	Cytoplasm By similarity.
Sequence similarities	Belongs to the pyruvoyl-dependent arginine decarboxylase family.
