Abstract

Serine-rich repeat glycoproteins (SRRPs) are conserved in Gram-positive bacteria. They are crucial for modulating biofilm formation and bacterial-host interactions. Glycosylation of SRRPs plays a pivotal role in the process; thus understanding the glycosyltransferases involved is key to identifying new therapeutic drug targets. The glycosylation of Fap1, an SRRP of Streptococcus parasanguinis, is mediated by a gene cluster consisting of six genes: gtf1, gtf2, gly, gtf3, dGT1, and galT2 Mature Fap1 glycan possesses the sequence of Rha1-3Glc1-(Glc1-3GlcNAc1)-2,6-Glc1-6GlcNAc. Gtf12, Gtf3, and dGT1 are responsible for the first four steps of the Fap1 glycosylation, catalyzing the transfer of GlcNAc, Glc, Glc, and GlcNAc residues to the protein backbone sequentially. The role of GalT2 and Gly in the Fap1 glycosylation is unknown. In the present study, we synthesized the fully modified Fap1 glycan in Escherichia coli by incorporating all six genes from the cluster. This study represents the first reconstitution of an exogenous stepwise O-glycosylation synthetic pathway in E. coli In addition, we have determined that GalT2 mediates the fifth step of the Fap1 glycosylation by adding a rhamnose residue, and Gly mediates the final glycosylation step by transferring glucosyl residues. Furthermore, inactivation of each glycosyltransferase gene resulted in differentially impaired biofilms of S. parasanguinis, demonstrating the importance of Fap1 glycosylation in the biofilm formation. The Fap1 glycosylation system offers an excellent model to engineer glycans using different permutations of glycosyltransferases and to investigate biosynthetic pathways of SRRPs because SRRP genetic loci are highly conserved.

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

  • Loss of glycosylation of the Fap1 serine-rich repeat adhesin with GalNAc, GlcNAc, and rhamnose of the oral commensal Streptococcus parasanguinis influences biofilm-forming ability.

    “For example, loss of glycosylation of the Fap1 serine-rich repeat adhesin with GalNAc, GlcNAc, and rhamnose of the oral commensal Streptococcus parasanguinis influences biofilm-forming ability.36–38”

    From The dental plaque biofilm matrix (2021) · cites this paper as [38]

    The Results report that disrupting Fap1 glycosyltransferases reduced biofilm formation in S. parasanguinis. But the paper describes the Fap1 glycan as containing rhamnose, glucose, and GlcNAc—not GalNAc—so the claim's inclusion of GalNAc is unsupported. The cited passages have section labels but no page numbers in our copy. (LLM, conf=0.90)

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.
