ADP-heptose is a molecule composed of adenosine diphosphate (ADP) linked to a heptose sugar molecule. Heptose sugars are commonly found in bacterial lipopolysaccharides (LPS) and are crucial for the structural integrity and immunogenicity of these molecules. ADP-heptose is involved in the biosynthesis of LPS, which is an essential component of the outer membrane of Gram-negative bacteria. LPS plays a critical role in bacterial virulence and host-pathogen interactions. Studying ADP-heptose can provide insights into bacterial physiology, pathogenesis, and potential targets for antibiotic development.
