Structure of the gene 2.5 protein, a single-stranded DNA binding protein encoded by bacteriophage T7.
The gene 2.5 protein (gp2.5) of bacteriophage T7 is a single-stranded DNA (ssDNA) binding protein that has essential roles in DNA replication and recombination. In addition to binding DNA, gp2.5 physically interacts with T7 DNA polymerase and T7 primase-helicase during replication to coordinate events at the replication fork. We have determined a 1.9-A crystal structure of gp2.5 and show that i...
متن کاملGene A product of phi X174 is required for site-specific endonucleolytic cleavage during single-stranded DNA synthesis in vivo.
A functional gene A product of phi X174 was found to be required at the stage of single-stranded DNA synthesis. A precursor complex that synthesizes single-stranded DNA (50S complex [Fujisawa and Hayashi, 1976]) was isolated from cells infected with wild-type or with temperature-sensitive gene A mutant phage. Proper cleavage of the single-stranded viral DNA did not occur in cells infected with ...
متن کاملChallenges to Design and Develop of DNA Aptamers for Protein Targets. I. Optimization of Asymmetric PCR for Generation of a Single Stranded DNA Library
Aptamers, or single stranded oligonucleotides, are produced by systematic evolution of ligands by exponential enrichment, abbreviated as SELEX. In the amplification and regeneration step of SELEX technique, dsDNA is conversed to ssDNA. Asymmetric PCR is one of the methods used for the generation of ssDNA. The purpose of this study was to design a random DNA library for selection of aptamers wit...

متن کاملC-terminal phenylalanine of bacteriophage T7 single-stranded DNA-binding protein is essential for strand displacement synthesis by T7 DNA polymerase at a nick in DNA.
Single-stranded DNA-binding protein (gp2.5), encoded by gene 2.5 of bacteriophage T7, plays an essential role in DNA replication. Not only does it remove impediments of secondary structure in the DNA, it also modulates the activities of the other replication proteins. The acidic C-terminal tail of gp2.5, bearing a C-terminal phenylalanine, physically and functionally interacts with the helicase...
