Refactoring bacteriophage T7
Natural biological systems are selected by evolution to continue to exist and evolve. Evolution likely gives rise to complicated systems that are difficult to understand and manipulate. Here, we redesign the genome of a natural biological system, bacteriophage T7, in order to specify an engineered surrogate that, if viable, would be easier to study and extend. Our initial design goals were to p...
متن کاملFlap endonuclease of bacteriophage T7
Gene 6 protein of bacteriophage T7 has 5'-3'-exonuclease activity specific for duplex DNA. We have found that gene 6 protein also has flap endonuclease activity. The flap endonuclease activity is considerably weaker than the exonuclease activity. Unlike the human homolog of gene 6 protein, the flap endonuclease activity of gene 6 protein is dependent on the length of the 5'-flap. This dependenc...
متن کاملSuperinfection exclusion by bacteriophage T7.
Only two of the early genes of bacteriophage T7 were found to play a significant role in exclusion of superinfecting bacteriophage T3 particles; genes 0.3 and 1. Protein synthesis by the preinfecting phage particle was not required for efficient exclusion. These findings are discussed with regard to the known functions of these genes during T7 development.
متن کاملBacteriophage T7 DNA polymerase – sequenase
An ideal DNA polymerase for chain-terminating DNA sequencing should possess the following features: (1) incorporate dideoxy- and other modified nucleotides at an efficiency similar to that of the cognate deoxynucleotides; (2) high processivity; (3) high fidelity in the absence of proofreading/exonuclease activity; and (4) production of clear and uniform signals for detection. The DNA polymerase...
متن کاملFrameshifting in gene 10 of bacteriophage T7.
Gene 10 of bacteriophage T7, which encodes the most abundant capsid protein, has two products: a major product, 10A (36 kDa), and a minor product, 10B (41 kDa). 10B is produced by frameshifting into the -1 frame near the end of the 10A coding frame and is incorporated into the capsid. The frameshift occurs at a frequency of about 10% and is conserved in bacteriophage T3. This study shows that s...
