Abstract
Significance Glycosyltransferase enzymes synthesize complex sugar-containing macromolecules that play pivotal roles in the biology of all cells. Bacteria produce a vast range of glycoconjugate structures that frequently dictate host–pathogen interactions. The composition and chain length of bacterial glycans are both important for biological function, yet the mechanisms for chain-length determination are generally poorly understood. Here, we describe a remarkable family of proteins in which each member contains multiple glycosyltransferase modules (often representing new glycosyltransferase families) for glycan polymerization and chain termination. The polymerase and terminator activities are separated by a molecular ruler that establishes product length. The modularity of these proteins provides an adaptable platform for generating antigenic diversity in nature and potential new strategies for glycoengineering.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
