PseudoCAP IBA-seed assessment

PTN node	node term	n_seeds	leaf IBAs	seed annotation (term, evidence, PMID)	verdict	rationale	other seeds	IBD stands without this seed?
PTN002160747	GO:0015288 porin activity	3	24 (6 taxa)	GO:0015288, IMP, PMID:2120174 (PseudoCAP)	INDIRECT-PHENOTYPE	Same paper and same problem as the oprD row: four OM proteins lost together, porin role assigned to "at least one". The term is correct for OprE by single-channel data (PMID:33481046). PSEUDOCAP WRONG_EVIDENCE_CODE/CHECK, PROBABLE.	OprD (P32722), OpdP (Q9HVS0)	Yes; stands on OprD (see oprD notes). No GO_CENTRAL defect.

The PseudoCAP IDA outer membrane row from the same paper is plausible (OM-protein profiles) and is
MODIFIED to cell outer membrane (GO:0009279).
