Characterization of lipopolysaccharides from Escherichia coli K-12 mutants.
Chemical analyses of the carbohydrate composition of lipopolysaccharides (LPS) from a number of LPS mutants were used to propose a schematic composition for the LPS from Escherichia coli K-12. The formula contains four regions: the first consists of lipid A, ketodeoxyoctonoic acid, and a phosphorous component; the second contains only heptose; the third only glucose; and the fourth additional g...

15 صفحه اولMechanism of adenine toxicity in Escherichia coli.
The mechanism of adenine toxicity in an hpt gpt strain of Escherichia coli that is extremely sensitive to adenine inhibition was investigated. Adenine-resistant derivatives had secondary mutations in adeninephosphoribosyltransferase or the purR repressor. Growth studies with various purine salvage pathway mutants and the ability of guanosine to prevent adenine toxicity indicated that adenine ex...
متن کاملThe Toxicity of Escherichia coli L-Asparaginase1
proposed that these quantitative differences in requirement for exogenous L-asparagine will serve as a unique system where therapy can be selectively directed against the sensitive tumor cell while sparing normal tissue. This communication, which presents the results of toxi cologic studies with various batches of L-asparaginase derived from E. coli, demonstrates the particular susceptibility o...
متن کاملToxicity of herbicides on Escherichia coli growth.
Agriculture uses a huge variety and quantity of chemicals. If, on one hand, the goal is to increase productivity, on the other hand these products contaminate aquatic environments. Among these products, herbicides deserve greater attention in relation to contamination of aquatic environments due to their extensive use to weed control. This study was carried out because the effects of these mole...
