متن کاملEnzymatic characterization of 17 L-arabinose negative mutants of Escherichia coli.
The linear order of 17 closely linked L-arabinose negative (nonutilizing) mutant sites on the genetic map of Escherichia coli strain B/r has been established by three factor transduction experiments, and was found to correspond completely with the organization of these mutants into three functional groups (A, B, and C) on the basis of growth and accumulation studies (Gross and Englesberg, 1959)...
متن کاملBase Analogue Induced Arabinose-negative Mutants of Escherichia Coli.
EOXYRIBONUCLEIC acid codes information as a specific linear sequence of the base pairs adenine-thymine (AT) and guanine-cytosine (GC) ( WATSON and CRICK 1953). Replacement of an AT pair by a GC pair, o r a GC pair by an AT pais may cause a visible mutation. A transition is a base-pair change as written above in which a purine replaces a purine, and a pyrimidine replaces a pyrimidine (FREESE 196...
متن کاملL-arabinose operon of Escherichia coli
TIG December 2000, volume 16, No. 12 559 Over forty years of research on the L-arabinose operon of Escherichia coli have provided insights into the mechanism of positive regulation of gene activity. This research also discovered DNA looping and the mechanism by which the regulatory protein changes its DNA-binding properties in response to the presence of arabinose. As is frequently seen in focu...
متن کاملDirect selection of L-arabinose negative mutants of Escherichia coli strain B@rl.
ROSS and ENGLESBERG (1959), using three and four factor transduction exG periments with phage PI bt, found that the mutational sites of 17 L-arabinose nonutilizing mutants of Escherichia coli were arranged in a linear sequence. The 17 mutants were divided into three distinct functional groups on the basis of biochemical analyses. Complete correspondence was found between the order of the mutati...
