Photosystem II Reconstitution into Proteoliposomes and Methodologies for Structure–Function Characterization
Bibliographic record
Abstract
This chapter discusses the photosystem II (PSII) reconstitution into proteoliposomes. In the first part of the chapter, protocols are outlined for the preparation of lipid bilayer vesicles (liposomes) constituted of individual thylakoid lipids or their mixtures, for the preparation of PSII particles, and for the incorporation of the PSII particles into the liposomes. In the second part of the chapter, methodologies are described for the structure-function characterization of the PSII-lipid complexes (proteoliposomes). This includes the sodium dodecylsulfate-polyacrylamide gel electrophoresis determination of the PSII proteins, the measurement of oxygen-evolving activity of PSII in the proteoliposomes, the study of structural changes of the PSII proteins upon their incorporation into the lipid bilayers by Fourier transform infrared (FT-IR) spectroscopy, and the characterization of the PSII activity by fluorescence induction.

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.
