Exempel på hur man kan använda TRANSPOSASE i en mening

• A transposase is any of a class of enzymes capable of binding to the end of a transposon and catalysing its movement to another part of a genome, typically by a cut-and-paste mechanism or a replicative mechanism, in a process known as transposition.
• Complete splicing of the introns produces the transposase enzyme, while alternative partial splicing of introns 1 and 2, leaving only intron 3 in the mRNA transcript, encodes the P element repressor.
• A composite transposon is similar in function to simple transposons and insertion sequence (IS) elements in that it has protein coding DNA segments flanked by inverted, repeated sequences that can be recognized by transposase enzymes.
• Initially discovered as a repressor of transposase, resolvase also plays a role in facilitating Tn3 replication (Sherratt 1989).
• Once the enzyme is bound to both ends of the transposon, the IR/DR sequences are brought together and held by the transposase in a Synaptic Complex Formation (SCF).
• piggyBac (PB) DNA transposons mobilize via a "cut-and-paste" mechanism whereby a transposase enzyme (PB transposase), encoded by the transposon itself, excises and re-integrates the transposon at other sites within the genome.
• This pseudoknot stimulates programmed -1 ribosomal frameshifting (PRF-1) which in turn stimulates the express of transposase, an enzyme required for transposition.
• If there is an old P element near the gene of interest (with a broken transposase) you can remobilise by microinjection of the embryo with coding for transposase or transposase itself.
• While the function of the protein is not fully understood by the scientific community, bioinformatic tools have shown that the protein bares much similarity to zinc finger or transposase proteins.
• As do all other Tc1/mariner-type transposases, SB transposase inserts a transposon into a TA dinucleotide base pair in a recipient DNA sequence.
• The PiggyBac (PB) transposon system employs a genetically engineered transposase enzyme to insert a gene into a cell's genome.
• TIRs, terminal inverted repeats, which allow transposase to recognize the transposon and excise/reintegrate it.
• The interaction of these transposases activates the complex; transposase makes double stranded breaks in the DNA and the transposon is fully excised.
• The transposase will bind to the terminal inverted repeats of the transposon and mediate synapsis of the transposon ends.
• The catalytic domain has the hallmark DDE (sometimes DDD) amino acids that are found in many transposase and recombinase enzymes.
• Regarding the piggyBac transposase, his laboratory has shown that the dimerization through the Ring Finger Domain present at the C-terminus attenuates the excision activity of this enzyme (Biochemistry, 2018, 57:2913).
• Tn5 is a transposase that cuts and ligates adapters to genomic regions unbound by nucleosomes (open chromatin).
• Next, these full-length cDNA molecules undergo a process called tagmentation facilitated byTn5 transposase preloaded with adaptors necessary for library amplification.
• This is followed by a process called tagmentation, in which double-stranded cDNA is fragmented and tagged using Tn5 transposase, which cleaves the cDNA and ligates adaptors for library amplification.
