  1. Pfu DNA polymerase

    For Plaque Forming Unit, see Plaque forming unit Pfu DNA polymerase is an enzyme found in the hyperthermophilic archaeon Pyrococcus furiosus , where it functions in vivo to replicate the organism s DNA . In vitro , Pfu is used to quickly amplify DNA in polymerase chain reaction PCR processes, where the enzyme serves the central function of copying a new strand of DNA during each extension step. Proofreading ability of Pfu polymerase The main difference between Pfu and alternative enzymes is Pfu s superior ... Taq DNA polymerase , Pfu DNA polymerase possesses 3 to 5 exonuclease proofreading activity, meaning that it works its way along the DNA from the 5 end to the 3 end and corrects nucleotide misincorporation errors. This means that Pfu DNA polymerase generated PCR fragments will have fewer errors than Taq generated PCR inserts. As a result, Pfu is more commonly used for molecular cloning of PCR fragments than the historically popular Taq. Commercially available Pfu typically results in an error ... Category EC 2.7.7 de Pfu Polymerase id Pfu DNA polimerase ... using PCR. However, Pfu is slower and typically requires 1&ndash 2 minutes per cycle to amplify 1kb of DNA at 72 C. Using Pfu DNA polymerase in PCR reactions also results in blunt ended PCR products. Pfu DNA polymerase is hence superior for techniques that require high fidelity DNA synthesis, but can also be used in conjunction with Taq polymerase to obtain the fidelity of Pfu with the speed of Taq polymerase activity. History Scientists associated with the biotech company Stratagene, based ... subsequently the superiority of Pfu over Taq in 1991, since they flamed it and it still retained its tertiary structure. They published their work as Lundberg et al., A High Fidelity Thermostable DNA Polymerase Isolated from Pyrococcus Furiosus, Strategies 4 34 35 1991 and Gene in December of that year ...

  1. DNA polymerase II

    Unreferenced stub auto yes date December 2009 DNA polymerase II also known as DNA Pol II or Pol II is a prokaryote prokaryotic DNA polymerase most likely involved in DNA repair . The enzyme is 90 kDa in size and is coded by the POLB polB gene . DNA Pol II can synthesize DNA new base pairs at an average rate of between 40 and 50 nucleotides second. Strains lacking the gene show no defect in growth or replication. Synthesis of Pol II is induced during the stationary phase of cell growth. This is a phase in which little growth and DNA synthesis occurs. It is also a phase in which the DNA can accumulate mutation damage such as short gaps, which act as a block to DNA Pol III . Under these circumstances, Pol II helps to overcome the problem because it can reinitiate DNA synthesis downstream of gaps. Pol II has a low error rate but it is much too slow to be of any use in normal DNA synthesis. Pol II differs from Pol I in that it lacks a 5 3 exonuclease activity, and cannot use a nicked duplex template. See also DNA replication . DNA polymerase .

  1. A-DNA

    Image A DNA orbit animated small.gif right frame The A DNA structure. A DNA is one of the many possible double helical structures of DNA . A DNA is thought to be one of three biologically active double helical structures along with B DNA B and Z DNA . It is a right handed double helix fairly similar to the more common and well known B DNA form, but with a shorter more compact helical structure. It appears likely that it occurs only in dehydrated samples of DNA, such as those used in crystallographic experiments, and possibly is also assumed by DNA RNA hybrid helices and by regions of double stranded RNA. Structure A DNA is fairly similar to B DNA given that it is a right handed double helix with major ... turn. This results in a deepening of the major groove and a shallowing of the minor.

From this, a triplet code of A DNA propensities was derived as energetic rules for predicting A DNA formation. This code correctly predicted 90 of A and B DNA sequences in crystals and correlates with A DNA formation in solution. Thus, with our previous studies on Z DNA, we now have a single method to predict the relative stability of sequences in the three standard DNA duplex conformations. ref name Basham1995 cite journal author Basham B, Schroth GP, Ho PS title An A DNA triplet code thermodynamic rules for predicting A and B DNA journal Proc Natl Acad Sci USA volume 92 issue 14 pages ... of the Most Common DNA Forms Image A DNA, B DNA and Z DNA.png right thumb Side view of A , B , and Z DNA.

  1. Polymerase stuttering

    Polymerase stuttering is the process by which a polymerase Transcription genetics transcribe s a nucleotide several times without progressing further on the mRNA chain. It is often used in addition of poly A tail s or 5 cap capping mRNA chains by less complex organism s such as viruses. Process A polymerase may undergo stuttering as a probability controlled event, hence it is not explicitly controlled by any mechanisms in the translation process. Generally, it is a result of many short repeated ribosomal frameshift frameshift s on a slippery sequence of nucleotide s on the mRNA strand ref Anderson EC, Hunt SL, Jackson RJ. Internal initiation of translation from the human rhinovirus 2 internal ribosome entry site requires the binding of Unr to two distinct sites on the 5 untranslated region. J Gen Virol. 2007 Nov 88 Pt 11 3043 52. ref . However, the frameshift is restricted to one in some cases two ref Mauro VP, Chappell SA, Dresios J.
