On the roles of methionine and the importance of its microenvironments in redox metalloproteins
Bibliographic record
Abstract
and in blue copper proteins. However, the roles of Met can go beyond a simple ligand. The thioether functional group of Met allows it to be considered as a hydrophobic residue as well as one that is capable of weak dipolar interactions. In addition, the lone pairs on sulphur allow Met to interact with other groups, inluding the aforementioned metal ions. Because of its properties, Met can play diverse roles in metal coordination, fine tuning of redox reactions, or supporting protein structures. These roles are strongly influenced by the nature of the surrounding medium. Herein, we describe several common interactions between Met and surrounding aromatic amino acids and how they affect the physical properties of both copper and iron metalloproteins. While the importance of interactions between Met and other groups is established in biological systems, less is known about their roles in redox metalloproteins and our view is that this is an area that is ready for greater attention.

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.
