The Spectral–Structural Relationship of a Series of Oxyluciferin Derivatives
Bibliographic record
Abstract
The absorption and emission spectra of a series of oxyluciferin derivatives with different substituents, as well as 6'-amino oxyluciferins in different enol and keto forms, with or without an active-site model of luciferase, were systematically investigated using density functional theory. The effects of substituents, microenvironment, and the luciferase on the structures, absorption spectra, and fluorescent emission were all taken into account. It was found that a wide range of emission colors can be obtained from various oxyluciferin derivatives with the inclusion of active site residues modeling the luciferase active site. Enol and keto forms are responsible for the emissions observed in experiments. It was suggested that the active site of luciferase must be included in the calculation in order to determine the form of the emitters.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
