Leucotoxin LukE

Gene

lukE

Organism
Staphylococcus aureus
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Part of a bi-component leucotoxin that acts by forming pores in the membrane of the target cells. LukE-LukD is as effective as the Panton-Valentine leucocidin (PVL) for inducing dermonecrosis when injected in the rabbit skin, but not hemolytic and poorly leucotoxic on human blood cells compared to other leucotoxins expressed by S.aureus.1 Publication

Expressioni

Inductioni

Expressed at the late exponential growth. Is cotranscribed with lukD.1 Publication

Interactioni

Subunit structurei

Toxicity requires sequential binding and synergistic association of a class S and a class F component which form heterooligomeric complexes (By similarity). LukE (class S) associates with LukD (class F). LukE can also associate with HlgB.By similarity1 Publication

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 one 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.
