The Bacterial Defensin Resistance Protein MprF Consists of Separable Domains for Lipid Lysinylation and Antimicrobial Peptide Repulsion 1 1¤ 2 2 1 Christoph M. Ernst , Petra Staubitz , Nagendra N.

MprF plays a crucial role in Staphylococcus aureus virulence and it is involved in resistance to the CAMP-like antibiotic daptomycin. MprF is a large membrane protein that modifies the anionic phospholipid phosphatidylglycerol with L-lysine, thereby diminishing the bacterial affinity for CAMPs. Its widespread
