CDP-glycerol glycerophosphotransferase family protein similar to Bacillus subtilis teichoic acid poly(glycerol phosphate) polymerase that catalyzes the addition of further 2-8 glycerol phosphate units from CDP-glycerol to the single glycerol phosphate unit bound to the prenolpyrophosphate-linked disaccharide
CDP-Glycerol:Poly(glycerophosphate) glycerophosphotransferase; Wall-associated teichoic acids are a heterogeneous class of phosphate-rich polymers that are covalently linked to the cell wall peptidoglycan of gram-positive bacteria. They consist of a main chain of phosphodiester-linked polyols and/or sugar moieties attached to peptidoglycan via a linkage unit. CDP-glycerol:poly(glycerophosphate) glycerophosphotransferase is responsible for the polymerization of the main chain of the teichoic acid by sequential transfer of glycerol-phosphate units from CDP-glycerol to the linkage unit lipid.

UDP-N-acetylglucosamine 2-epimerase and similar proteins; Bacterial members of the UDP-N-Acetylglucosamine (GlcNAc) 2-Epimerase family (EC 5.1.3.14) are known to catalyze the reversible interconversion of UDP-GlcNAc and UDP-N-acetylmannosamine (UDP-ManNAc). The enzyme serves to produce an activated form of ManNAc residues (UDP-ManNAc) for use in the biosynthesis of a variety of cell surface polysaccharides; The mammalian enzyme is bifunctional, catalyzing both the inversion of stereochemistry at C-2 and the hydrolysis of the UDP-sugar linkage to generate free ManNAc. It also catalyzes the phosphorylation of ManNAc to generate ManNAc 6-phosphate, a precursor to salic acids. In mammals, sialic acids are found at the termini of oligosaccharides in a large variety of cell surface glycoconjugates and are key mediators of cell-cell recognition events. Mutations in human members of this family have been associated with Sialuria, a rare disease caused by the disorders of sialic acid metabolism. This family belongs to the GT-B structural superfamily of glycoslytransferases, which have characteristic N- and C-terminal domains each containing a typical Rossmann fold. The two domains have high structural homology despite minimal sequence homology. The large cleft that separates the two domains includes the catalytic center and permits a high degree of flexibility.

UDP-N-acetylglucosamine 2-epimerase; This family consists of UDP-N-acetylglucosamine 2-epimerases EC:5.1.3.14 this enzyme catalyzes the production of UDP-ManNAc from UDP-GlcNAc. Note that some of the enzymes is this family are bifunctional such as Swiss:O35826 and Swiss:Q9Z0P6 in this instance Pfam matches only the N-terminal half of the protein suggesting that the additional C-terminal part (when compared to mono-functional members of this family) is responsible for the UPD-N-acetylmannosamine kinase activity of these enzymes. This hypothesis is further supported by the assumption that the C-terminal part of Swiss:O35826 is the kinase domain.
