Computational approaches to enzymatic reaction assignment: a review of methods, validations, and future directions
Bibliographic record
Abstract
Characterizing the proteins and molecules that underpin cellular metabolism is fundamental to advancing our understanding of biological processes. However, the rapidly expanding repertoire of newly identified proteins and metabolites presents significant challenges for experimental characterization and functional analysis. Computational approaches can be used to identify and elucidate catalytic relationships between enzymes and their substrates and provide powerful tools that support biological research and applications in biochemical engineering, and drug discovery. In this review, we describe the problem of reaction assignment for predicting enzymatic reactions leveraging structural, network, and high-throughput experimental data. Also considered are theoretical perspectives motivating the design of computational methods, available resources, and validation techniques. Current and future computational approaches for enzymatic reaction assignment are expected to advance in tandem with technologies for experimental analysis of metabolism, such as metabolomics, and flux-based methods, to expand our understanding of metabolism.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
