  • 功能：
    Highly processive DNA-dependent RNA polymerase that catalyzes the transcription of class II and class III viral genes. Recognizes a specific promoter sequence and enters first into an 'abortive phase' where very short transcripts are synthesized and released before proceeding to the processive transcription of long RNA chains. Unwinds the double-stranded DNA to expose the coding strand for templating. Participates in the initiation of viral DNA replication presumably by making primers accessible to the DNA polymerase, thus facilitating the DNA opening. Plays also a role in viral DNA packaging, probably by pausing the transcription at the right end of concatemer junction to allow packaging complex recruitment and beginning of the packaging process.

    1. Using correlation analysis, it was found that the promoter strength characterized by reporter gene expression was closely correlated with rupture force and the binding percentage of T7 RNA polymerase by force spectroscopy. PMID: 29187520
    2. From the docking of the minimum energy representative structures of T7 lysozyme at different pH strengths (obtained from the free energy landscape analysis) with T7RNAP structures at same pH strengths, we saw strong interaction patterns at pH 7.9 and pH 5. PMID: 28545576
    3. Data suggest that comparative transcriptional fidelities/mutation rates for DNA-directed RNA polymerases are as follows: human mitochondrial POLRMT [2x10(-5)]; Saccharomyces cerevisiae mitochondrial Rpo41 [6x10(-6)]; phage T7 single-subunit RNA polymerase [2x10(-6)]. PMID: 28882896
    4. Molecular dynamics simulation study described the behavior of the two magnesium ions in RNAP activity during genetic transcription. PMID: 28205291
    5. The control of the discrimination between dNTP and rNTP in DNA and RNA polymerases has been described. PMID: 27480935
    6. The study provides evidence that the intrinsic infidelity of T7 RNAP in transcription brings significant phenotypic consequences, observed as frameshift mutation restoration and the production of a heterogenous population of the full-length protein. PMID: 25824942
    7. We show here that DNA-protein cross-links constitute strong but not absolute blocks to in vitro transcription catalyzed by T7 RNAP. PMID: 22235136
    8. Hydrogen bonds of RNA polymerase play an important role in the efficiency of transcription. PMID: 22044042
    9. introducing a nuclear transgene, ST7, encoding a light-regulated plastid-targeted T7RNAP by cross-pollination. PMID: 15517992
    10. T7 promoter-polymerase interaction weakening facilitates promoter release PMID: 15711016
    11. An amino acid substitution weakens promoter binding but markedly reduces abortive cycling over a variety of initial sequences. PMID: 15831591
    12. structure activity relationship PMID: 16301518
    13. Active T7RNAP elongation by showing that both rapidly elongating and halted complexes are equally sensitive to pyrophosphate. PMID: 16516229
    14. Collapse of the DNA from the downstream end of the bubble is a major contributor to the characteristic instability of the abortive T7 RNA polymerase transcription complex. PMID: 16790422
    15. Poto-regulation of transcription reaction by azobenzene-tethered promoter was attributed to the change of binding property of RNAP to the promoter by trans-cis isomerization of azobenzene. PMID: 17150558
    16. transition to an elongation complex by T7 RNA polymerase is a multistep process PMID: 17548349
    17. site-specifically tethered chemical nucleases and functional characterization of directed T7 RNAP mutants to both reveal the architecture of the duplex DNA PMID: 17580086
    18. G-rich sequences located in the transcribed strand do not affect transcription by either polymerase, but when the sequences are located in the non-transcribed strand, they partially arrest both polymerases PMID: 18292094
    19. study reports crystal structures of T7 RNAP bound to promoter DNA containing either a 7- or an 8-nucleotide (nt) RNA transcript that illuminate intermediate states along the transition pathway PMID: 18948533
