NAD biosynthesis from 2-amino-3-carboxymuconate semialdehyde
gomodel:YeastPathways_PWY-5653
NAD biosynthesis from 2-amino-3-carboxymuconate semialdehyde in Saccharomyces cerevisiae S288C cyclizes 2-amino-3-carboxymuconate-6-semialdehyde to quinolinic acid, converts quinolinic acid to nicotinate D-ribonucleotide, adenylates nicotinate D-ribonucleotide to deamido-NAD through NMA1 or NMA2 nicotinate-nucleotide adenylyltransferase activity, and amidates deamido-NAD with glutamine to form NAD.

Curation history
- Codex; review-causal-graph; Reviewed every native GO-CAM fact; preserved precise input/output, causal, location, membership and complex-part relations with traceable structured source evidence. Kept distinct generic physical instances and recorded source-scope exclusions in the cohort review ledger.

Reviewed all 5 activity location assignments and 4 mapped physical proteins against reviewed S288C UniProt release2026_03 location/function/caution batch SHA256 95f72dcc644358c480e0e59f996cf88533558b5fa4256460a030e0a1eaf9678d. Added 5 independently supported location edges and quarantined 1 generic cytosol source assertions. Mapped physical protein locations via exact SGD cross-references; retained source ECO grades, molecular form and conditional notes. Physical protein location alone never generates activity location. Explicitly inspected functional assertions support bounded activity projections. Every original activity location and exclusion is recorded in reports/causal_graph_review/gocam-location-review.json. No independent location annotation is treated as an evidence gap, not a negative result. Cytoplasm is not narrowed to cytosol. Microsome fractions are not projected as in-vivo organelles. Semantic validation passed all85 records;4 independent source-role acceptance tests passed.
