  • Patent number: 9005579
    Abstract: The present invention relates to methods and compositions for use in modulating, including inhibiting the growth and/or reducing the virulence of gram-positive bacteria. The present invention provides methods and compositions for disrupting the cell wall and/or cell membrane in gram-positive bacteria such that cell wall or cell membrane target(s) are rendered exposed or accessible and sensitive to a modulation thereof. Methods for modulation of one or more gram-positive bacterial cell wall or cell membrane targets in a gram-positive bacteria are provided comprising disrupting the cell wall such that the cell wall or cell membrane target, which is particularly a sortase, is rendered exposed or accessible and sensitive to a modifying, modulating or binding agent, which is particularly an antibody or fragment thereof, wherein the cell wall or cell membrane target is inaccessible or relatively insensitive to the modifying, modulating or binding agent in the absence of cell wall disruption.

  • Publication number: 20140073639
    Abstract: The application describes targets and methods that can inhibit bacterial growth in Gram-positive and Gram-negative bacteria. A bacterial enzyme, 2-epimerase, is common to both Gram-positive and Gram-negative bacteria and contains an allosteric site that can be targeted to disrupt the enzyme. The allosteric site is present on the bacterial 2-epimerase, but the analogous mammalian enzyme does not contain the allosteric site, providing a route for attacking bacterial infections without affecting the mammalian enzyme.
