Lactoferrin and transferrin damage of the gram-negative outer membrane is modulated by Ca2+ and Mg2+.

Abstract

Lactoferrin and transferrin have antimicrobial activity against selected Gram-negative bacteria, but the mechanism of action has not been defined. We studied the ability of lactoferrin and transferrin to damage the Gram-negative outer membrane. Lipopolysaccharide release by the proteins could be blocked by concurrent addition of Ca2+ and Mg2+. Addition of… (More)
