The genetic transformation machinery: composition, localization, and mechanism
Abstract
Natural genetic transformation is widely distributed in bacteria. It is a genetically programmed process that is inherent to the species. Transformation requires a specialized membrane-associated machinery for uptake of exogenous double-stranded DNA. It also requires dedicated cytosolic proteins, some of which have been characterized only recently, for the processing of internalized single-stranded DNA fragments into recombination products. A series of observations made in Bacillus subtilis and Streptococcus pneumoniae led to the recent emergence of a picture of a unique, highly integrated machine localized at the cell poles. This dynamic machine, which we propose to name the transformasome, involves both membrane and cytosolic proteins, to internalize, protect, and process transforming DNA. This review attempts to summarize these recent observations with special emphasis on the early stages in DNA processing.

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.
