Compartment-specific control of phosphoinositide lipids is essential for cell function. The Sac1 lipid phosphatase regulates endoplasmic reticulum (ER) and Golgi phosphatidylinositol-4-phosphate [PI(4)P] in response to nutrient levels and cell growth stages. During exponential growth, Sac1p interacts with Dpm1p at the ER but shuttles to the Golgi during(More)
The lipid A and core regions of the lipopolysaccharide in Rhizobium leguminosarum, a nitrogen-fixing plant endosymbiont, are strikingly different from those of Escherichia coli. In R. leguminosarum lipopolysaccharide, the inner core is modified with three galacturonic acid (GalA) moieties, two on the distal 3-deoxy-D-manno-octulosonic acid (Kdo) unit and(More)
The lipid A and inner core regions of Rhizobium leguminosarum lipopolysaccharide contain four galacturonic acid (GalA) residues. Two are attached to the outer unit of the 3-deoxy-D-manno-octulosonic acid (Kdo) disaccharide, one to the mannose residue, and one to the 4'-position of lipid A. The enzymes RgtA and RgtB, described in the accompanying article,(More)
