Formation of complexes between long tail fibres and substructural elements of phage T4D.
Complexes of substructural elements of bacteriophage T4 (baseplates, baseplate-core complexes) with long tail fibres were obtained for the first time by complementation in vitro. A study of the organization of the complexes was carried out by PAGE, electron microscopy and sedimentation analysis. About 90% of baseplates and baseplate-core complexes were combined with fibres. However, the number ...
متن کاملRegion-specific recombination in phage T4. III. The effect of host mutations on glucosylation-dependent recombination in bacteriophage T4D.
Mutations in the Escherichia coli genes recK, recL and (probably) uvrE and polA increase special (glucosylation-dependent), but not general recombination in bactriophage T4D.
متن کاملDifferential selection of acridine resistance mutations in human DNA topoisomerase IIbeta is dependent on the acridine structure.
Type II DNA topoisomerases are targets of acridine drugs. Nine mutations conferring resistance to acridines were obtained by forced molecular evolution, using methyl N-(4'-(9-acridinylamino)-3-methoxy-phenyl) methane sulfonamide (mAMSA), methyl N-(4'-(9-acridinylamino)-2-methoxy-phenyl) carbamate hydrochloride (mAMCA), methyl N-(4'-(9-acridinylamino)-phenyl) carbamate hydrochloride (AMCA), and ...
متن کاملdistribution of phage types and transferable drug resistance in shigellae
a total of 610 strains of shigellae isolated from cases of diarrhea in iran during 1962-73 were studied with respect to their phage type, as well as antibiotic resistance and transferable drug resistance along with serotyping. it was shown that there was some relation between serotypes and phage types but no association could be found between phage types and resistance pattern.
متن کاملPolynucleotide ligase in bacteriophage T4D recombination.
Following infection of E. coli B with ligase-deficient rII bacteriophage T4D recombination between linked markers is increased 4.2 fold and heterozygote frequency increased 2.3 fold. In such infection recombination occurs at a rapid rate for an extended period. This is in contrast to the time course of recombination observed in wild-type, lysis-inhibited, or lysis-defective (gene t defective) i...
