A DltE-DltD-DltX interaction network regulates lipoteichoic acid D-alanylation and Lactiplantibacillus plantarum-mediated growth promotion in Drosophila.
D-alanylation of teichoic acids is a conserved modification of Gram-positive bacterial cell envelopes that modulates resistance to environmental stresses and host interactions. While the cytosolic steps of this pathway are well characterized, the extracellular reactions responsible for transferring D-alanine onto teich...
