Expression, purification, crystallization and preliminary X-ray analysis of Rv3117, a probable thiosulfate sulfurtransferase (CysA3) from<i>Mycobacterium tuberculosis</i>
Bibliographic record
Abstract
The gene product of open reading frame Rv3117 from Mycobacterium tuberculosis (Mtb) strain H37Rv is annotated as encoding a probable rhodanese-like thiosulfate sulfurtransferase (MtbCysA3). MtbCysA3 was expressed and purified and then crystallized using the sitting-drop vapour-diffusion method. X-ray diffraction data were collected and processed to a maximum resolution of 2.5 A. The crystals belong to the monoclinic space group P2(1), with unit-cell parameters a = 38.86, b = 91.43, c = 83.57 A, beta = 96.6 degrees . Preliminary diffraction data shows that two molecules are present in the asymmetric unit; this corresponds to a V(M) of 2.4 A(3) Da(-1).
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.
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.
