Abstract
Protein phosphorylation is known to occur across all three kingdoms of life; however, the study of posttranslational modification in bacteria was neglected for a considerable amount of time. Early attempts to detect its presence were unsuccessful, generating the dogma that protein phosphorylation was a regulatory mechanism that emerged late in evolution to meet the needs of organisms composed of multiple and differentiated cells. The pioneering work of several groups in the 1970s identified protein kinase activity in both Escherichia coli and Salmonella typhimurium (1 – 3), which soon led to the discovery of the histidine/aspartate kinases of the two-component systems (4, 5). The first aspect of this system involves the stimulation of a histidine kinase by a particular environmental or intracellular signal resulting in autophosphorylation on a key histidine residue. The phospho-histidine can then be used as a substrate by the cognate response regulator for its own autophosphorylation on an aspartate residue. The majority of response regulators are DNA binding proteins that trigger expression from target promoters. Unlike the cross-reactivity observed with serine/threonine/tyrosine (Ser/Thr/Tyr) kinases in eukaryotic cell signaling cascades, two-component systems work in isolation, where a given pairing of histidine kinase and response regulator is highly selective for each other via protein-protein interaction.

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 it
