377 results about "Variome" patented technology

The variome is the whole set of genetic variations found in populations of species that have gone through a relatively short evolution change. For example, among humans, about 1 in every 1,200 nucleotide bases differ. However, as the human species diverged only 10,000 years ago, this variation rate is comparatively small. In practice, the variome can be the sum of the single nucleotide polymorphisms (SNPs) of the population. The Human Variome Project seeks to compile this genetic variation data worldwide. Variomics is the study of variome and a branch of bioinformatics.

Dideoxynucleotide-triphosphate utilization by the hyper-thermophilic DNA polymerase from the archaeon Pyrococcus furiosus

Polymerases from the Pol I family which are able to efficiently use ddNTPs have demonstrated a much improved performance when used to sequence DNA. A number of mutations have been made to the gene coding for the Pol II family DNA polymerase from the archaeon Pyrococcus furiosus with the aim of improving ddNTP utilisation. "Rational" alterations to amino acids likely to be near the dNTP binding site (based on sequence homologies and structural information) did not yield the desired level of selectivity for ddNTPs. However, alteration at four positions (Q472, A486, L490 and Y497) gave rise to variants which incorporated ddNTPs better than the wild type, allowing sequencing reactions to be carried out at lowered ddNTP:dNTP ratios. Wild type Pfu-Pol required a ddNTP:dNTP ratio of 30:1; values of 5:1 (Q472H), 1:3 (L490Y), 1:5 (A486Y) and 5:1 (Y497A) were found with the four mutants; A486Y representing a 150-fold improvement over the wild type. A486, L490 and Y407 are on an alpha-helix that lines the dNTP binding groove, but the side chains of the three amino acids point away from this groove; Q472 is in a loop that connects this alpha-helix to a second long helix. None of the four amino acids can contact the dNTP directly. Therefore, the increased selectivity for ddNTPs is likely to arise from two factors: 1) Small overall changes in conformation that subtly alter the nucleotide triphosphate binding site such that ddNTPs become favoured; 2) interference with a conformational change that may be critical both for the polymerisation step and discrimination between different nucleotide triphosphates.
