Group II introns as controllable gene targeting vectors for genetic manipulation of bacteria

Karberg, Michael, Guo, Huatao, Zhong, Jin, Coon, Robert, Perutka, Jiri, Lambowitz, Alan M.·2001·Nature Biotechnology

Abstract

Mobile group II introns can be retargeted to insert into virtually any desired DNA target. Here we show that retargeted group II introns can be used for highly specific chromosomal gene disruption in Escherichia coli and other bacteria at frequencies of 0.1-22%. Furthermore, the introns can be used to introduce targeted chromosomal breaks, which can be repaired by transformation with a homologous DNA fragment, enabling the introduction of point mutations. Because of their wide host range, mobile group II introns should be useful for genetic engineering and functional genomics in a wide variety of bacteria.

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.
