Analysis of the mobilization region of the broad-host-range IncQ-like plasmid pTC-F14 and its ability to interact with a related plasmid, pTF-FC2.
Plasmid pTC-F14 is a 14.2-kb plasmid isolated from Acidithiobacillus caldus that has a replicon that is closely related to the promiscuous, broad-host-range IncQ family of plasmids. The region containing the mobilization genes was sequenced and encoded five Mob proteins that were related to those of the DNA processing (Dtr or Tra1) region of IncP plasmids rather than to the three-Mob-protein sy...
متن کاملIsolation of a new broad-host-range IncQ-like plasmid, pTC-F14, from the acidophilic bacterium Acidithiobacillus caldus and analysis of the plasmid replicon.
A moderately thermophilic (45 to 50 degrees C), highly acidophilic (pH 1.5 to 2.5), chemolithotrophic Acidithiobacillus caldus strain, f, was isolated from a biooxidation process used to treat nickel ore. Trans-alternating field electrophoresis analysis of total DNA from the A. caldus cells revealed two plasmids of approximately 14 and 45 kb. The 14-kb plasmid, designated pTC-F14, was cloned an...
متن کاملThe Universal K3 Surface of Genus 14 via Cubic Fourfolds
Using Hassett’s isomorphism between the Noether-Lefschetz moduli space C26 of special cubic fourfolds X ⊂ P of discriminant 26 and the moduli space F14 of polarized K3 surfaces of genus 14, we use the family of 3-nodal scrolls of degree seven in X to show that the universal K3 surface over F14 is rational.
متن کاملPlasmid evolution and interaction between the plasmid addiction stability systems of two related broad-host-range IncQ-like plasmids.
Plasmid pTC-F14 contains a plasmid stability system called pas (plasmid addiction system), which consists of two proteins, a PasA antitoxin and a PasB toxin. This system is closely related to the pas of plasmid pTF-FC2 (81 and 72% amino acid identity for PasA and PasB, respectively) except that the pas of pTF-FC2 contains a third protein, PasC. As both pTC-F14 and pTF-FC2 are highly promiscuous...
متن کاملInhibition versus potentiation of ligand-gated ion channels can be altered by a single mutation that moves ligands between intra- and intersubunit sites.
Pentameric ligand-gated ion channels (pLGICs) are similar in structure but either inhibited or potentiated by alcohols and anesthetics. This dual modulation has previously not been understood, but the determination of X-ray structures of prokaryotic GLIC provides an ideal model system. Here, we show that a single-site mutation at the F14' site in the GLIC transmembrane domain turns desflurane a...
