Antifreeze proteins from snow mold fungi
Bibliographic record
Abstract
The psychrophilic fungi Coprinus psychromorbidus and Typhula ishikariensis produced unique antifreeze proteins (AFPs) in the extracellular space. Molecular masses of purified fungal AFPs of C. psychromorbidus and T. ishikariensis were approximately 22 and 23 kDa, respectively. Cloned genes of AFPs from T. ishikariensis do not have any similarity with known proteins. Purified fungal AFPs from cultural filtrate of T. ishikariensis and recombinant fungal AFP from methylotrophic yeast formed specific ice crystals resembling "Stone Age knives". These observations indicate that fungal AFPs do not form proper hexagonal ice crystals to inhibit their growth and that fungal AFPs can probably bind to surfaces of ice crystals in an irregular manner.Key words: antifreeze protein, snow mold fungi, Coprinus psychromorbidus, Typhula ishikariensis.

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.
