Abstract:Bacteria synthesize numerous types of sphingolipids with various physiological functions. Despite their roles in mediating host inflammation, cellular differentiation, and protection from environmental stress, their biosynthetic pathway remains undefined since several essential eukaryotic ceramide synthesis enzymes have no bacterial homologue. Using genetic and biochemical approaches, we identified the complete pathway for bacterial ceramide synthesis. Bioinformatic and phylogenetic analyses revealed the prese… Show more
