Abstract

fetched live from OpenAlex

Nucleocidin is a rare example of naturally occurring nucleoside containing fluorine and sulfamate substituents. Identification of Streptomyces strains that are better producers of nucleocidin has facilitated the trek towards elucidating the biosynthesis of this novel molecule. For the first time gene inactivation experiments have identified three genes, nucGIJ, encoding two predicted sulfatases and a radical SAM enzyme, that are essential for sulfamate biosynthesis. This opens the door to further functional analysis of the biosynthetic gene cluster encoding nucleocidin. More information can be found in the Research Article by D. L. Zechel et al.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
