An allylic adenosine triphosphate analog (AATP) was tested as a substrate for commercially available DNA polymerases. All but one of the enzymes assayed incorporated AATP opposite thymidine (T) with concomitant termination of the elongation reaction. A concentration of only 1 microM was sufficient for complete termination of the polymerization reaction for a short template mediated by Ampli Taq...
To the Editor: Recently Muglia et al. [1] reported in your journal a nonisotopic detection of (CAG)n repeats in the Huntington disease (HD) gene. We have read this article with great interest, as we use a similar method for the detection of the above [2, 3]. There are many difficulties in the PCR conditions of examining CAG repeats in the HD gene and in the detection of PCR products on nondenat...
Obesity is one of the most commonly identified factors for the obstructive sleep apnea syndrome (OSAS). Adipose tissue is the source of many cytokines, among them there are IL-6, IL-1, and TNF-alpha. The level of inflammatory cytokines increases in people with OSAS and obesity. The aim of this study was to evaluate the distribution of genotypes in inflammatory cytokine genes in people with obes...
The Applied Biosystems PRISM fluorescence-based genotyping system as well as the Invitrogen TA Cloning vector system are influenced by the tendency of Taq DNA polymerase to add an adenine nucleotide to the 3' end of PCR products after extension. Incomplete addition of adenine to a majority of PCR product strands creates problems in allele-calling during genotyping and potentially diminishes the...
PCR co-amplification of two distinct HIV1 tat gene sequences lead to the formation of recombinant DNA molecules. The frequency of such recombinants, up to 5.4% of all amplified molecules, could be decreased 2.7 fold by a 6 fold increase in Taq DNA polymerase elongation time. Crossover sites mapped essentially to three discrete regions suggesting specific Taq DNA polymerase pause or termination ...
The structure of Leishmania major pteridine reductase (PTR1) in complex with NADPH and the inhibitor 2,4,6-triaminoquinazoline (TAQ) has been solved in a new crystal form by molecular replacement and refined to 2.6 A resolution. The inhibitor mimics a fragment, the pterin head group, of the archetypal antifolate drug methotrexate (MTX) and exploits similar chemical features to bind in the PTR1 ...
