Origin of DNA replication of bacteriophage f1 as the signal for termination.
Restriction fragments that contain the origin of DNA replication of bacteriophage f1 were inserted in vitro into circular f1 DNA molecules to form genomes that contain two origins. This DNA was used to transfect Escherichia coli. Analyses of the DNA of the progeny phage indicated that one origin and the DNA segment located between the two origins in the infecting DNA molecules had been eliminat...
متن کاملNucleotide sequence of the O gene and of the origin of replication in bacteriophage lambda DNA.
The nucleotide sequence of the O gene in bacteriophage lambda DNA is presented. According to two possible initiator codons, the primary structure of the O protein deduced from the DNA sequence consists of 278 or 299 amino acid residues. Structure and function of the O protein--one of the two phage initiator proteins for lambda DNA replication--are discussed in the light of a secondary structure...
متن کاملIllegitimate recombination at the replication origin of bacteriophage M13.
Hybrids composed of phage M13 and plasmid pHV33 were used to study the formation of deletions in Escherichia coli. Eighty to ninety percent of the deletion endpoints were at the position of the nick introduced into the M13 replication origin by the phage gene II protein. This suggests the existence of a novel mechanism of illegitimate recombination.
متن کاملThe nucleotide sequence of the replication origin of plasmid NTP1.
The sequence of the DNA of the origin region of NTP1 has been obtained. Analysis of the sequence indicates that: (1) there is great sequence homology in the DNA upstream from the origin in NTP1, ColE1, CLODF13, PBR345 AND PBR322; (2) only seven base pairs of NTP1 are identical with the sequence downstream from the origin in ColE1, although some homology exists for 140 bases downstream; (3) two ...
