Promoters are a vital component of expression vectors because they control the binding of RNA polymerase to DNA. RNA polymerase transcribes DNA to mRNA which is ultimately translated into a functional protein.

cognate base pairs during promoter recognition. The single subunit DNA-dependent RNA polymerases (RNAPs) that are encoded by bacteriophage T7 and its relatives (e.g., T3, SP6, K11) are highly specific for their individual promoter sequences (for review, see ref. 3). Al-though each promoter consensus sequence is related to a

lacUV5-promoter fragment was produced by PCR with the primers 5′-CTCACTCATTAGGCACCCCAGGC-3′ and 5′-CCAGGCGGTGAAGGGCAATCAGC-3′ from template The high specificity of T7 RNA polymerase (RNAP) for its promoter sequence is mediated, in part, by a specificity loop (residues 742–773) that projects into the DNA binding cleft (1). Previous work demonstrated a role for the amino acid residue at position 748 (N748) in this loop in discrimination of the base pairs (bp) at positions −10 and −11 (2). A comparison of the sequences of other Se hela listan på differencebetween.com T3 RNA Polymerase is a DNA-dependent RNA polymerase that synthesizes RNA using only T3 DNA or DNA templates cloned downstream from a T3 promoter.

DNA Polymerase vs RNA Polymerase - this lecture explains about the difference between DNA polymerase and RNA polymerase. 1.DNA polymerase synthesizes DNA whi

The DNA polymerase beta promoter-directed CAT expression was competitively inhibited by the simultaneous transfection of plasmid DNA containing SV40 early promoter sequence. The viral sequences which are competitive to the GC-box of DNA polymerase beta gene promoter were the GC-boxes of SV40 promoter. The ability of a promoter to initiate transcription is important for the control of gene expression. Mutations in the DNA polymerase beta (po1β) promoter may affect the transcription of this gene; however, the relationship between these mutations and the upregulation of the expression of po1β remains unclear. In the designation of structurally characterized complexes, R stands for RNA polymerase, P stands for promoter DNA, and c and o indicate closed and open complexes, respectively (where strand separation has not or has occurred, respectively). The binding of a multisubunit RNA polymerase (RNAP) or general transcription factors to a specialized transcription promoter DNA sequence is an essential step in initiating DNA transcription in all organisms (1, 2).
