Isolation and characterization of bacteriophage T4 base plates.
A method for isolating bacteriophage T4 base plates from lysates of Escherichia coli B cells infected with the ts mutant in gene 19, ts B31 has been developed. By electrophoresis in polyacrylamide gel with sodium dodecyl sulfate the base plates have been shown to contain five to seven protein components with molecular weights of 36,000, 53,000, 66,000, 81,000, 87,000, and probably about 100,000...
متن کاملIsolation and characterization of the bacteriophage T4 tail-associated lysozyme.
Direct evidence has been obtained that the tail-associated lysozyme of bacteriophage T4 (tail-lysozyme) is gp5, which is a protein component of the hub of the baseplate. Tails were treated with 3 M guanidine hydrochloride containing 1% Triton X-100, and the tail-lysozyme was separated from other tail components by preparative isoelectric focusing electrophoresis as a peak with a pI of 8.4. The ...
متن کاملIsolation and characterization of conditional alleles of bacteriophage T4 genes uvsX and uvsY.
The bacteriophage T4 uvsW, uvsX and uvsY gene functions are required for wild-type levels of recombination and for normal survival and mutagenesis after treatments with ultraviolet (UV) and ionizing radiations. The ability of uvsX and uvsY mutations to suppress the lethality of gene 49 mutations was used to select temperature-sensitive and amber alleles of these two genes. (uvsW mutations do no...
متن کاملIsolation and Genomic Characterization of the T4-Like Bacteriophage PM2 Infecting Pectobacterium carotovorum subsp. carotovorum
In order to control Pectobacterium carotovorum subsp. carotovorum, a novel virulent bacteriophage PM2 was isolated. Bacteriophage PM2 can infect 48% of P. carotovorum subsp. carotovorum and 78% of P. carotovorum subsp. brasilliensis but none of atrosepticum, betavasculorum, odoriferum and wasabiae isolates had been infected with PM2. PM2 phage belongs to the family Myoviridae, and contains a la...
متن کاملThe isolation and characterization of Stenotrophomonas maltophilia T4-like bacteriophage DLP6
Increasing isolation of the extremely antibiotic resistant bacterium Stenotrophomonas maltophilia has caused alarm worldwide due to the limited treatment options available. A potential treatment option for fighting this bacterium is 'phage therapy', the clinical application of bacteriophages to selectively kill bacteria. Bacteriophage DLP6 (vB_SmoM-DLP6) was isolated from a soil sample using cl...
