Phosphatidylcholine (PC) is the most abundant phospholipid in eukaryotic membranes, whereas only a limited number of bacteria are able to synthesize PC. Intriguingly, many of the bacteria with PC-containing membranes interact with eukaryotic hosts. PC is one of the major membrane lipids in the phytopathogenic bacterium Agrobacterium tumefaciens. The(More)
Pseudomonas aeruginosa is an opportunistic pathogen which causes a variety of diseases, including respiratory tract infections in patients suffering from cystic fibrosis. Therapeutic treatment of P. aeruginosa infections is still very difficult because the bacteria exhibit high intrinsic resistance against a variety of different antibiotics and, in(More)
Phosphatidylcholine (PC) is the major phospholipid in eukaryotic membranes. In contrast, it is found in only a few prokaryotes including members of the family Rhizobiaceae. In these bacteria, PC is required for pathogenic and symbiotic plant-microbe interactions, as shown for Agrobacterium tumefaciens and Bradyrhizobium japonicum. At least two different(More)
Phosphatidylcholine (PC, lecithin) has long been considered a solely eukaryotic membrane lipid. Only a minority of all bacteria is able to synthesize PC. The plant-transforming bacterium Agrobacterium tumefaciens encodes two potential PC forming enzymes, a phospholipid N-methyltransferase (PmtA) and a PC synthase (Pcs). We show that PC biosynthesis and(More)
Phosphatidylcholine (PC), a typical eukaryotic membrane phospholipid, is present in only about 10% of all bacterial species, in particular in bacteria interacting with eukaryotes. A number of studies revealed that PC plays a fundamental role in symbiotic and pathogenic microbe-host interactions. Agrobacterium tumefaciens mutants lacking PC are unable to(More)
Phosphatidylcholine (PC) is the major phospholipid in eukaryotic membranes. In contrast, it is found in only a limited number of bacteria including members of the Rhizobiales. Here, PC is required for pathogenic and symbiotic plant-microbe interactions, as shown for Agrobacterium tumefaciens and Bradyrhizobium japonicum, respectively. Two different(More)
