| PTN node | node term | n_seeds | leaf IBAs | seed annotation (term, evidence, PMID) | verdict | rationale | other seeds | IBD stands without this seed? |
|---|---|---|---|---|---|---|---|---|
| PTN001839150 | GO:0006598 polyamine catabolic process | 4 | 10 (4 taxa) | GO:0006598, IMP, PMID:21622750 (PseudoCAP) | SOUND | pauA3 mutant retarded on 1,3-diaminopropane; GO has no DAP-catabolism term, so the general term is right. | E. coli PuuA P78061 (IMP putrescine catabolism, IDA glutamate-putrescine ligase, PMID:18495664); SpuB Q9I6J3 (SOUND); SpuI Q9I6J5 (WRONG reference) | Yes |
No PSEUDOCAP or GO_CENTRAL defect. Shared node with spuI and spuB (same
batch); the node-level judgment is identical in all three: the IBD stands on
PuuA, PauA3 and PauA2 even though SpuI's seed rows are mis-referenced (defects
recorded on spuI only).
The L-glutamine biosynthetic process IBA (PTN000464978, GlnA seed) and the
glutamine synthetase IEA are marked over-annotated / modified consistently on
all three PauA genes.
