Molecular characterization of a surface protein antigen gene from serotype c Streptococcus mutans, implicated in dental caries

Okahashi, N., Sasakawa, C., Yoshikawa, M., Hamada, S., Koga, T.·1989·Molecular Microbiology

Abstract

Summary: The complete nucleotide sequence of the gene for a cell‐surface protein antigen (PAc) of Streptococcus mutans MT8148 (serotype c) was determined. The pac gene consisted of 4695 bp and coded for a 170 773 D protein. The pac gene product contained a putative 38 amino acid signal peptide, resulting in a 166817D mature protein. A potential promoter sequence and a putative Shine‐Dalgarno sequence preceded the open reading frame. Two internal repeating amino acid sequences were present in the PAc. One repeating region located in the N‐terminal region was rich in alanine, and the other located in the central region was rich in proline. Southern blot analysis under the less stringent condition (allowing up to 35% base mismatch) revealed that the probe covering the prolinerich region hybridized to DNA preparations from strains of Streptococcus cricetus, Streptococcus sobrinus and Streptococcus downei as well as Streptococcus mutans.

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.
