Biosynthesis of wall teichoic acids. The following metabolic intermediates that occur in other pathways are labeled in blue: undecaprenyl phosphate (Fig. 10), UDP N-acetylglucosamine (UDP-GlcNAc) (Fig. 10), CDP-glycerol (this figure), and glycerol-3-phosphate (G3P) (Fig. 6). UDP-ManNAc, UDP-N-acetylmannosamine.
