Abstract

The Xer site-specific recombination system acts at ColE1 cer and pSC101 psi sites to ensure that these plasmids are in a monomeric state prior to cell division. We show that four proteins, ArgR, PepA, XerC and XerD are necessary and sufficient for recombination between directly repeated cer sites on a supercoiled plasmid in vitro. Only PepA, XerC and XerD are required for recombination at psi in vitro. Recombination at cer and psi in vitro requires negative supercoiling and is exclusively intramolecular. Strand exchange at cer produces Holliday junction-containing products in which only the top strands have been exchanged. This reaction requires the catalytic tyrosine residue of Xer C but not that of XerD. Recombination at psi gives catenated circular resolution products. Strand exchange at psi is sequential. XerC catalyses the first (top) strand exchange to make a Holiday junction intermediate and XerD catalyses the second (bottom) strand exchange.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The 11-kb LIR encoded a tyrosine recombinase that belonged to the integrase family.

    “The 11-kb LIR encoded a tyrosine recombinase that belonged to the integrase family.43 , 44”

    From Whole genomic DNA sequencing and comparative genomic analysis of<i>Arthrospira platensis</i>: high genome plasticity and genetic diversity (2016) · cites this paper as [44]

    The Introduction (page unavailable) describes XerC and XerD as recombinases related to the lambda integrase family and identifies their catalytic tyrosine. It calls them chromosomally encoded; it does not identify an 11-kb LIR or say that the LIR encoded a recombinase. (LLM, conf=0.85)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
