UniProtKB - Q04473 (RTX3B_ACTPL)
Protein
Toxin RTX-III translocation ATP-binding protein
Gene
apxIIIB
Organism
Actinobacillus pleuropneumoniae (Haemophilus pleuropneumoniae)
Status
Functioni
Involved in the transport of the toxin RTX-III.
Miscellaneous
The sequence shown is that of serotype 2.
Caution
Tyr-13 is present instead of the conserved Cys which is expected to be the active site residue of peptidase C39. Thus they are presumed to be without peptidase activity.Curated
