Pyruvoyl-dependent arginine decarboxylase AaxB

Gene

aaxB

Organism
Chlamydia pneumoniae (Chlamydophila pneumoniae)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

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.1 Publication

Catalytic activityi

L-arginine = agmatine + CO2.

Cofactori

pyruvateNote: Binds 1 pyruvoyl group covalently per subunit.

Enzyme regulationi

Inhibited by argininamide.

Kineticsi

  1. KM=5.0 mM for L-arginine1 Publication

    pH dependencei

    Optimum pH is 3.4.1 Publication

    Temperature dependencei

    Thermostable. Retains 48% activity at 50 degrees Celsius, and 13% activity at 100 degrees Celsius.1 Publication
