Strategies and Tools for Detection of Protein S-Nitrosylation and S-Sulfhydration
Bibliographic record
Abstract
H 2 S interacts with the free thiol group in the active cysteine residues from target proteins and forms a hydropersulfide moiety (-SSH), termed as S-sulfhydration, which is similar to nitric oxide (NO) regulation of protein by S-nitrosylation. Protein S-sulfhydration now is proposed to mediate most of H 2 S bioactivities in various cellular functions. A number of methods have been developed for detection of S-nitrosylation and S-sulfhydration. Selective recognition of hydropersulfide (SSH) is a main target for the detection of S-sulfhydration. Protein Ssulfhydration can be detected by biotin switch assay, which is developed and further modified based on the detection approaches for protein S-nitrosylation. Here we highlight the different tools for detection of protein S-sulfhydration and S-nitrosylation, and provide strategies for developing new methods to locate the modified cysteine residues.

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.
