Abstract

fetched live from OpenAlex

Escherichia coli leucyl tRNA synthetase (LeuRS) is one of aminoacyl tRNA synthetases (aaRSs) and belongs to class 1 aaRSs. The apparent steady state kinetics of the aminoacylation reaction catalyzed by LeuRS in the presence of some RE 3+ were studied. The results show that Mg 2+ can be substituted by RE 3+ for the aminoacylation reaction. The apparent K m values for ATP and leucine are markedly different between native and Mg 2+ free tRNA 1 Leu . At high concentration of ATP there is inhibitory effect on Mg 2+ free tRNA but not on native tRNA, which indicates that metal ions are a substrate of the aminoacylation reaction.

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.

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.
