The origin of purine and pyrimidine deoxyribose in T6r+ bacteriophage.
Lanning and Cohen (1) reported that when Escherichia coli strain B is infected with T6r+ bacteriophage in a medium containing glucose-1-Cr4, the deoxyribose from the deoxyribonucleic acid of the T6rf particles liberated on lysis of the cells contains 40 to 60 per cent of the specific activity of the exogenous glucose. In parallel experiments, it was shown that the deoxyribose from the deoxyribo...

Bacteriol. 92:1670-1679. 1966.-The thymineless, histidineless, uracil-less Escherichia coli 15 THU was shown to be sensitive to streptomycin, dying in patterns comparable to that of strain 15 TAU in the presence or absenc...
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 کاملIn Vitro Biocontrol of Escherichia coli Through the Immobilization of its Specific Lytic Bacteriophage on Cellulose Acetate Biodegradable Film
Background and Aims: Bacteriophages are mandatory bacterial parasites that are harmless to human and animal, which are used by dipping or spraying in food as natural antimicrobial agents. The use of these methods leads to wasting or trapping of phage in food, but its immobilization on the polymer surface facilitates the contact of phage with the host cell at the food surface. Therefore, the aim...
متن کاملBiosynthesis 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...
