Function

[LUKEV_STAA8] Part of a bi-component leucotoxin that acts by forming pores in the membrane of the target cells. The activity of LukEv-LukDv to rabbit leukocytes is similar to that of the Panton-Valentine leucocidin (PVL). LukEv-LukDv is hemolytic to rabbit red blood cells although the activity is only 8% of gamma-hemolysin.^[1]

Publication Abstract from PubMed

Staphylococcal leukotoxins are a family of beta-barrel, bicomponent, pore-forming toxins with membrane-damaging functions. These bacterial exotoxins share sequence and structural homology and target several host-cell types. Leukotoxin ED (LukED) is one of these bicomponent pore-forming toxins that Staphylococcus aureus produces in order to suppress the ability of the host to contain the infection. The recent delineation of the important role that LukED plays in S. aureus pathogenesis and the identification of its protein receptors, combined with its presence in S. aureus methicillin-resistant epidemic strains, establish this leukocidin as a possible target for the development of novel therapeutics. Here, the crystal structures of the water-soluble LukE and LukD components of LukED have been determined. The two structures illustrate the tertiary-structural variability with respect to the other leukotoxins while retaining the conservation of the residues involved in the interaction of the protomers in the bipartite leukotoxin in the pore complex.
