A recombination module was identified within the insertion, which comprised a tyrosine recombinase (int, catalyses integration and excision), its cognate excisionase (xis), and a putative topoisomerase (rep, replication initiation factor).
WeatCliFS intends to catalyse an integration of activity of many existing programs on hydrometeology, on natural hazards and extreme events, on agriculture and food security and on disaster risk reduction.
Mr Zetsche and Wolfgang Bernhard were flown in from Germany to wield the axe.Nobody foresaw that it would take a crisis at Chrysler to catalyse the belated integration of the two companies.
Site specific recombinases are being developed as tools for "in vivo" genetic engineering because they can catalyse precise excision, integrations, inversions, or translocations of DNA between their distinct recognition target sites.
In this context, the "myth" of Latrun derived from the frustrations and the death of the new immigrants and was catalysed by their integration in a society where "the survivor of Shoah carried the new collective memory, immigrant refugees who had troubled pasts, and then were confronted with hostility and threat and still took their place with their blood and taking part in the war".
HIV-1 integrase (IN) catalyses the retroviral integration process, removing two nucleotides from each long terminal repeat and inserting the processed viral DNA into the target DNA.
Like phage integrases, it acts as a site-specific recombinase that catalyses both excision and integration [6].
Deep sequencing data for integration reactions catalysed by EcoCas1 in vitro did reveal a marked preference for a guanine at position −2 in the integration site (Nuñez et al., 2015).
The common consensus drawn by these studies is that viral vector integration is an active process catalysed by the tethering of the viral preintegration complex to open chromatin regions in the host cell genome as characterized by DNaseI hypersensitive sites and epigenetics marks (Cattoglio et al, 2010; Deichmann et al, 2011; Felice et al, 2009).
Although the −1 position might also be expected to play a role in the selection of integration sites, deep sequencing data for integration catalysed by EcoCas1 revealed no sequence preference at this position (Nuñez et al., 2015).
