Identification and initial characterization of carbonic anhydrase deletion mutants of Arabidopsis
Bibliographic record
Abstract
Carbonic anhydrase (CA; 4.2.1.1) is a zinc metalloenzyme that catalyzes the reversible hydration of CO2 to bicarbonate. Three families of CA, designated alpha, beta, and gamma, have been identified based on sequence comparisons. All three of these families are represented in the Arabidopsis genome, analysis of which has revealed that as many as 14 putative CA isoforms exist, 6 of these are members of the alpha family, 5 of the beta family and 3 of the gamma family. The purpose of this investigation was to initiate a functional genomics approach to the study of Arabidopsis CAs. This was accomplished by the identification of T-DNA insertion mutants in the putative CAs, the initial characterization of one of these mutants, beta-CA2, and the use of bioinformatics tools to predict the sequence conservation, phylogenetic relationship and subcellular locations of the putative Arabidopsis CAs.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
