Pyruvoyl-dependent arginine decarboxylase AaxB

Gene

aaxB

Organism
Chlamydia trachomatis serovar L2 (strain 434/Bu / ATCC VR-902B)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

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 (By similarity).By similarity

Catalytic activityi

L-arginine = agmatine + CO2.

Cofactori

pyruvateBy similarityNote: Binds 1 pyruvoyl group covalently per subunit.By similarity

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into Uniref entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
