Biosynthesis of phosphatidyl glycerophosphate in Escherichia coli.
An enzyme (L-glycerol 3-phosphate: CMP phosphatidyltransferase) catalyzing the synthesis of phosphatidyl glycerophosphate from CDP-diglyceride and L-glycerol 3-phosphate has been rendered soluble by treatment of the particulate, membrane-containing fraction of E. coli with Triton X-100 and has been partially purified. The enzyme, devoid of phosphatidyl glycerophosphatase activity, is specific f...
متن کاملIn vivo proteolytic degradation of the Escherichia coli acyltransferase HlyC.
Escherichia coli hemolysin (HlyA) is the prototype toxin of a major family of exoproteins produced by Gram-negative bacteria known as "repeats in toxins." Only fatty acid-acylated HlyA molecules at residues Lys564 and Lys690 are able to damage the target cell membrane. Fatty acylation of pro-HlyA is dependent on the co-synthesized acyltransferase HlyC and the acylated form of acyl-carrier prote...
متن کاملOverexpression of Peanut Diacylglycerol Acyltransferase 2 in Escherichia coli
Diacylglycerol acyltransferase (DGAT) is the rate-limiting enzyme in triacylglycerol biosynthesis in eukaryotic organisms. Triacylglycerols are important energy-storage oils in plants such as peanuts, soybeans and rape. In this study, Arachis hypogaea type 2 DGAT (AhDGAT2) genes were cloned from the peanut cultivar 'Luhua 14' using a homologous gene sequence method and rapid amplification of cD...
متن کاملPurification and characterization of glycerophosphate acyltransferase from rat liver mitochondria.
Glycerophosphate acyltransferase (GAT) catalyzes the conversion of sn-glycerol 3-phosphate to lysophosphatidic acid (LPA), the first and committed step of triacylglycerol and phospholipid synthesis. In spite of the important regulatory roles GAT may play in this biosynthetic pathway, little information is available on the structure, biochemical properties, and regulation of GAT from eukaryotic ...
متن کاملLocalization of Macromolecules in Escherichia Coli
The distribution of RNA in cells of E. coli 15 T(-)U(-) labeled with uridine-H(3) was studied by methods involving the analysis of radioautographic grain counts over random thin cross-sections and serial sections of the cells. The results were correlated with electron microscope morphological data. Fractionation and enzyme digestion studies showed that a large proportion of the label was found ...
