title: Regulation of type II fatty acid synthase in Gram-positive bacteria.
abstract: Bacterial cells stringently regulate the synthesis of their membrane phospholipids but the responsible mechanisms are incompletely understood. Recent biochemical, genetic and structural analyses have greatly expanded the knowledge of lipid metabolism in Gram-positive bacteria, revealing that these organisms use novel mechanisms to regulate this essential pathway. A remarkable progress was the identification of a new pathway for the initiation of phospholipid biosynthesis that uncovered a mechanism that coordinates fatty acid and phospholipid biosynthesis. Recent advances in structure determination of a global transcription factor have led to significant insights of the underlying complexities and functional elegance of membrane lipid homeostasis in Gram-positive bacteria.
