Abstract
Abstract Polyprotein processing is a controlled cascade of proteolytic events carried out by virally encoded cysteine proteinases. It plays a central role in the infectious life cycle of animal RNA viruses such as picornaviruses, caliciviruses, and coronaviruses. Furthermore, some of these viral enzymes are vitally important in viral RNA genome replication, virion assembly, and virus–host antagonism. The 3 C pro and 3 C‐like (3CL pro ) peptidases are structurally related to the chymotrypsin branch of the serine proteinase family, but they have the catalytic serine residue replaced by a cysteine. Their uniquely designed yet structurally conserved S1 substrate binding pocket strongly favors a P1‐Glutamine in the substrate. The high level of structural conservation in the active sites of 3 C pro and 3CL pro and the lack of a mammalian homolog make these enzymes hotly pursued targets for antiviral drug design. The structures of these viral cysteine peptidases in complex with various inhibitors have shed light not only on how different inhibitors work but also on the catalytic mechanisms underlying the hydrolysis of normal peptidyl substrates. Most importantly, the results from the structural studies on Hepatitis A virus (HAV) 3 C pro point out possible new directions in the design of therapeutic intervention in a variety of diseases caused by members of these large RNA virus families.

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.
