| PTN001254814 | GO:0022857 transmembrane transporter activity | 2 | 118 (36 taxa) | GO:0015562, IDA/IMP, PMID:19906986, PMID:21035449, PMID:22187978, PMID:23766114 (PseudoCAP) | E. coli MacB P75831 | Yes (MacB is an experimentally characterized ABC exporter) | SOUND | Mutants of any pump component trap pyoverdine in the periplasm; PvdT is the energizing IM component. Generic node term suits a MacB-like clade exporting different substrates. |
Shared nodes: pvdR (membrane fusion protein) and opmQ (outer membrane factor) belong to other PANTHER families and do not share PTN001254814, so no node-level defect is shared.
Defects: PSEUDOCAP WRONG_TERM on GO:0002049 pyoverdine biosynthetic process (PROBABLE; indirect phenotype, row does not seed a worklist IBD). No GO_CENTRAL defect.
