Cardiolipin Prevents Membrane Translocation and Permeabilization by Daptomycin

Zhang, TianHua; Muraih, Jawad K.; Tishbi, Nasim; Herskowitz, Jennifer; Victor, Rachel L.; Silverman, Jared; Uwumarenogie, Stephanie; Taylor, Scott D.; Palmer, Michael; Mintzer, Evan (American Society for Biochemistry and Molecular Biology, 2014-04-25)

Daptomycin is an acidic lipopeptide antibiotic that, in the presence of calcium, forms oligomeric pores on membranes containing phosphatidylglycerol. It is clinically used against various Gram-positive bacteria such as ...
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, ...
