May catalyze the final step in cell wall teichoic acid biosynthesis, the transfer of the anionic cell wall polymers (APs) from their lipid-linked precursor to the cell wall peptidoglycan (PG). Cell wall biogenesis. Interacts with MreB. Single mutant has no effect on cell growth or morphology under normal growth conditions. Triple disruption of tagTUV genes is not viable. Belongs to the LytR/CpsA/Psr (LCP) family.
