WebPhosphatidylcholine was identified by chromatographic, chemical and enzymatic degradation methods. On enzymatic hydrolysis with phospholipase A 2 and phospholipase C, lysophosphatidylcholine and phosphorylcholine were formed, respectively. Alkaline hydrolysis gave glycerophosphorylcholine. WebUnique mutants of Escherichia coli K-12, defective in phosphatidylglycerol synthesis, have been isolated from a temperature-sensitive strain incubated at its nonpermissive temperature. The parent strain had excess phosphatidylglycerol by harboring both the pss-1 allele [coding for a temperature-sensitive phosphatidylserine synthase (EC 2.7.8.8 ...

WebJan 1, 2004 · Lysylphosphatidylglycerol (LPG) is a basic phospholipid in which l-lysine from lysyl-tRNA is transferred to phosphatidylglycerol (PG). This study examined whether the Staphylococcus aureus mprF gene encodes LPG synthetase. A crude membrane fraction prepared from wild-type S. aureus cells had LPG synthetase activity that depended on PG …
WebPhosphatidylglycerol (PG) is a major lipid in many bacterial membranes, but comprises only 1–2 mol% of phospholipids in animal tissues. However, PG is much more abundant (~10 … WebA unique feature of plastid phosphatidylglycerol (PG) is a trans-double bond specifically at the sn-2 position of 16C fatty acid (16:1t- PG), which is catalyzed by FATTY ACID DESATURASE 4 (FAD4). To offer additional insights about the in vivo roles of FAD4 and its product 16:1t-PG, FAD4 overexpression lines (OX-FAD4s) were generated in Arabidopsis …
WebNov 21, 1975 · Studies on mechanism of phosphatidylglycerol synthesis in vitro revealed (in these two fractions) CDP-diglyceride and sn-glycerol phosphate precursors to phosphatidylglycerol phosphate, that hydrolysed to phosphatidylglycerol. In microsomes disaturated CDP-diglycerides were 1.6-1.9 times more active substrates than in …
