Abstract
P450 enzymes are of high interest for synthetic applications due to their ability to catalyze hydroxylation reactions at inactivated C-H bonds. The low solubility of many substrates in buffer, however, is limiting the applications of P450s. Our recent demonstration that the P450 enzymes CYP2D6 and CYP3A4 can function very well in biphasic solvent systems is one step towards overcoming this drawback, but is not practical when substrates or products are unstable in water, or with water-soluble products. An alternative strategy, which also facilitates enzyme recycling, is to directly resuspend lyophilized enzyme into nearly anhydrous organic solvents. Interestingly, we report here that CYP2D6 colyophilized with trehalose and suspended in n-decane shows higher activity than in aqueous buffer. This study demonstrates the unexpected high tolerance of CYP2D6 to some low water organic solvents and provides an alternative strategy to facilitate the use of this enzyme in synthesis.

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.
