Sequences of three promoters for the bacteriophage SP6 RNA polymerase.
Fragments of SP6 DNA generated by cleavage with Hpa II or Taq I were cloned into the Cla I site of pBR322 and the recombinant plasmids were screened for the presence of SP6 promoter activity by transcription in vitro with purified SP6 RNA polymerase. Three plasmids having promoter activity and small inserts of SP6 DNA were characterized. Hybridization studies showed that all three cloned promot...
متن کاملIdentification of bacteriophage K11 genomic promoters for K11 RNA polymerase.
Only one natural promoter that interacts with bacteriophage K11 RNA polymerase has so far been identified. To identify more, in the present study restriction fragments of the phage genome were individually assayed for transcription activity in vitro. The K11 genome was digested with two 4-bp-recognizing restriction enzymes, and the fragments cloned in pUC119 were assayed with purified K11 RNA p...
متن کاملNucleotide sequence and expression of the cloned gene of bacteriophage SP6 RNA polymerase.
The coding region of the gene for bacteriophage SP6 RNA polymerase was cloned into pBR322, and its entire nucleotide sequence was deduced. The predicted amino acid sequence for the polymerase consists of 874 amino acid residues with a total molecular weight of 98,561 daltons. Comparison of the amino acid sequence with that of T7 RNA polymerase reveals that regions with partial homology are pres...
متن کاملThe effect of a bacteriophage T4-induced polypeptide on host RNA polymerase interaction with promoters.
After infection of Escherichia coli with bacteriophage T4, the host RNA polymerase acquires several small phage-induced polypeptides (Stevens, A. (1974) Biochemistry 13, 493-503) and its alpha subunits get ADP-ribosylated by a virus-specific enzyme (Zillig, W., Mailhammer, R., Skorko, R., and Rohrer, H. (1977) Curr. Top. Cell. Regul. 12, 263-271). The modified polymerase displays changed enzyma...
متن کاملKinetic measurements of Escherichia coli RNA polymerase association with bacteriophage T7 early promoters.
During infection of Escherichia coli by bacteriophage T7, E. coli RNA polymerase utilizes only three promoters (A1, A2, and A3). In vitro, the A promoters predominate at very low polymerase concentration, but at higher polymerase concentration the minor B, C, D, and E promoters are used with equal efficiency. The binding constant for the initial association of polymerase with promoters and the ...
