Tyrosine residues (Tyr22) in Cas1 subunits bracket the foreign genetic material, acting as a ruler that limits the central dsDNA region of the protospacer to a length of 23 nucleotides.
“Tyrosine residues (Tyr22) in Cas1 subunits bracket the foreign genetic material, acting as a ruler that limits the central dsDNA region of the protospacer to a length of 23 nucleotides (nt) [20,27].”

In E. coli, Cas1 and Cas2 form a symmetric heterohexameric protein complex (Cas1-Cas2) that is required for spacer acquisition, featuring two Cas1 dimers and a single Cas2 dimer.
“In E. coli, the most widely studied adaptation model, Cas1 and Cas2 form a symmetric heterohexameric protein complex (Cas1-Cas2) that is required for spacer acquisition, featuring two Cas1 dimers (Cas1a, Cas1a’, Cas1b and Cas1b’) and a single Cas2 dimer [20].”

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.
