Recently proposed nomenclature for wall teichoic acid intermediates

Shown is the nomenclature proposed for wall teichoic acid biosynthetic intermediates (17). Intermediates were named according to the enzyme utilizing the molecule as a substrate. Lipid α is the substrate for TagA, Lipid β is the substrate for TagB. Lipid ϕ.n species are substrates for TagF where n indicates the number of glycerol phosphate residues in the molecule. For example, Lipid ϕ.1 is the product of the TagB-catalyzed priming reaction where a single glycerol phosphate residue is added. und, undecaprenol; P, phosphate; GroP, sn-glycerol-3-phosphate.

Enzyme	Substrate	Chemical composition
TagA	Lipid α	GlcNAc-1-P-P-und
TagB	Lipid β	ManNAc-β(1–4)-GlcNAc-1-P-P-und
TagF	Lipid ϕ.n	(GroP)n-ManNAc-β(1–4)-GlcNAc-1-P-P-und
TagF	Lipid ϕ.n analog	(GroP)n-ManNAc-β(1–4)-GlcNAc-1-P-P-tridecane
