Abstract
Disclose herein is a novel recombinant mutant protein of human Group IIA phospholipase A (PLA2) which has enhanced antibacterial activity when compared to the wild-type human Group IIA PLA2, pharmaceutical formulations comprising the protein and methods of use thereof. Additionally, the formulations may comprise other bioactive compounds, such as, e.g., conventional antibiotics, that act additively or synergistically with Group IIA PLA2 in order to promote bacterial killing.
Claims8
