An Acyl-Linked Dimer of Daptomycin Is Strongly Inhibited by the Bacterial Cell Wall
Taylor, Robert; Scott, Bradley; Taylor, Scott D.; Palmer, Michael (American Chemical Society, 2017-03-28)The lipopeptide antibiotic daptomycin is active against Gram-positive pathogens. It permeabilizes bacterial cell membranes, which involves the formation of membrane-associated oligomers. We here studied a dimer of daptomycin ... -
The Lipopeptide Antibiotic Daptomycin: Its Interaction With Calcium And Membranes And The Effects Of Membrane Lipid Composition On Its Activity
Taylor, Robert (University of Waterloo, 2018-01-22)Daptomycin (Dap) is a calcium-dependent cyclic lipodepsipeptide antibiotic used clinically to treat infections with pathogenic Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA). It targets ... -
Mechanistic studies on the effect of membrane lipid acyl chain composition on daptomycin pore formation
Beriashvili, David; Taylor, Robert; Kralt, Braden; Abu Mazen, Nooran; Taylor, Scott D.; Palmer, Michael (Elsevier, 2018-11-01)Daptomycin is a lipopeptide antibiotic that binds and permeabilizes the cell membranes of Gram-positive bacteria. Membrane permeabilization requires both calcium and phosphatidylglycerol (PG) in the target membrane, and ... -
Two successive calcium-dependent transitions mediate membrane binding and oligomerization of daptomycin and the related antibiotic A54145
Taylor, Robert; Butt, Khalida; Scott, Bradley; Zhang, TianHua; Muraih, Jawad K.; Mintzer, Evan; Taylor, Scott D.; Palmer, Michael (Elsevier, 2016-09)Daptomycin and A54145 are homologous lipopeptide antibiotics that permeabilize the cell membranes of Gram-positive bacteria. Membrane permeabilization depends on the presence of both phosphatidylglycerol (PG) and calcium, ...
