Construction of Rhodococcus random mutagenesis libraries using Tn5 transposition complexes.
The ability to generate tagged mutants of Rhodococcus spp. will facilitate a deeper understanding of this medically and commercially important genus. The absence of efficient transposon systems in these organisms has here been overcome by the use of Tn5-based DNA-protein transposition complexes which can transpose at high efficiency. To achieve this, electroporation efficiencies and antibiotic ...
متن کاملConcerted formation of macromolecular Suppressor-mutator transposition complexes.
Transposition of the maize Suppressor-mutator (Spm) transposon requires two element-encoded proteins, TnpA and TnpD. Although there are multiple TnpA binding sites near each element end, binding of TnpA to DNA is not cooperative, and the binding affinity is not markedly affected by the number of binding sites per DNA fragment. However, intermolecular complexes form cooperatively between DNA fra...

هدف از این مطالعه طراحی یک روش کلی برای سنتز یک سری از کمپلکس های دو هسته ای متقارن سیکلومتاله شده پلاتین (ii) بوده که دارای یک لیگاند پل زن(1,2-bis[bis(pentafluoro-phenyl)phosphino]ethane),dfppe, است. از واکنش cis-[pt(r)2(sme2)2]، که در آنr= para-tolyl ، با یک اکی والان از لیگاند benzo[h]quinoline,bhq، در استون محصول [pt(r)(bhq)(sme2)] که در آن r= para-tolyl بدست می آید. همچنین از واکنش 5/0 اک...
FUZZY TRANSPOSITION HYPERGROUPS
In this paper we introduce the notions of fuzzy transposition hypergroupsand fuzzy regular relations and investigate their basic properties.We also study fuzzy quotient hypergroups of a fuzzy transposition hypergroup.
متن کاملReconstructing Repairs of Census Data Forms as Database Repairs
In the context of consistent query answering (CQA) from inconsistent databases, the notion of repair is fundamental. A repair is a new database instance that minimally differs from the original, inconsistent database, but does satisfy the integrity constraints. Minimality usually refers to a minimal set of tuples on which the two instances differ. In this paper we reexamine the process of corre...
