Literature

pauA1-pauA7 encode PuuA homologues of the gamma-glutamylation pathway
PMID:21622750.
pauA3B2 participate in DAP catabolism PMID:21622750.
PMC full text (fetch summary): pauA3 = PA1566; the pauA3 mutant's growth on
DAP is retarded; growth on Put, Cad, Spd normal. No purified-enzyme assay.

PseudoCAP IBA-seed assessment

Other seeds' experimental support queried live in QuickGO on 2026-11-05.

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.
