Biosynthesis of ribose and deoxyribose in Escherichia coli.
The studies reported here are concerned with the biosynthesis of ribose and deoxyribose in Escherichia coli R-2. When these studies were undertaken the evidence available allowed no general conclusions to be drawn as to a common biosynthetic pathway for the two pentoses. Since that time numerous studies have contributed to a better understanding of the problem. Tracer studies on the origin of r...
متن کاملBiosynthesis of pentose in Escherichia coli. Synthesis of deoxyribose in cells infected with bacteriophage.
The biosynthesis of ribose and deoxyribose in Escherichia coli involves both the oxidative pathway through 6-phosphogluconate and the nonoxidative pathway through the transketolase and transaldolase sequence (Lanning and Cohen, 1954; Bernstein, 1956; Bagatell, Wright, and Sable, 1959). The proportions of the oxidative and nonoxidative pathways depend on the nature of the principal carbon source...
متن کاملEnzyme Biosynthesis in Escherichia Coli
Escherichia coli B synthesized beta-galactosidase and an enzyme system for D-xylose when exposed to lactose and xylose respectively in nitrogen-free media. The amount of beta-galactosidase formed in the absence of external nitrogen depended upon the nature of the medium in which the cells had originally been grown. Half as much of this enzyme was synthesized without exogenous nitrogen by cells ...
متن کاملEffect of Concomitant Lycopene Biosynthesis on CoQ10 Accumulation in Transformed Escherichia coli Strains
CoQ10 and lycopene are isoprenoid compounds with nutraceutical and pharmaceutical benefits. In this study, the effect of concomitant lycopene biosynthesis on CoQ10 accumulation in transformed Escherichia coli DH5α was studied. A lycopene production pathway including geranylgeranyl diphosphate synthase (crtE), phytoene synthase (crtB), and phytoene desaturase (crtI) from Erwinia herbicola was co...
متن کاملBiosynthesis 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...
