Teichoic acids are anionic polymers comprising polyol phosphates as indispensable components of the main chain. They are the most abundant and the best studied class of Gram-positive cell wall components. About 10 genes encoding enzymes involved in teichoic acid biosynthesis have been characterized (Neuhaus and Baddiley, 2003; Swoboda et al., 2010) Teichoic acids are polyesters of phosphoric acid. There is a large variety of these polymers, but the common feature is a phosphoryl group in the backbone. Teichoic acids are major components of cell walls and are responsible for a number of functions, including the flux of ions through the membranes [ 293 ] Teichoic acid is a structure found exclusively in gram-positive bacterial cell walls. This acid is formed through the joining of either glycerol phosphate or ribitol phosphate groups linked together with phosphodiester bonds. This structure is a polysaccharide with an overall negative charge
