Abstract

Significance: Sialic acid (Sia) residues are essential monosaccharides in mammals and confer multiple biological functions. Their precise generation is important for both structure–function studies and biotechnological applications. We describe a unique technology that enables the controlled generation of protein sialylation in Nicotiana benthamiana . The plant engineering approach relies on a combination of endogenous glycan deconstruction and the introduction of human sialylation capabilities. An arrangement of transgenic and transient expression modules resulted in the targeted synthesis of Sia structures in three different linkage types, reaching a polymerization degree exceeding 40 residues (polySia). Importantly, the obtained functional activities of polySia point to novel biotherapeutic applications. Our results highlight the exceptional flexibility of the plant-based expression platform for engineering complex posttranslational protein modifications.

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.
