Operon context PMID:18833300.
UniProt: NCBIfam metI; PANTHER PTHR30450:SF1 D-methionine transport system

PTN000765163	GO:0006865 amino acid transport	2	8 (7 taxa)	GO:1903810, IMP, PMID:18833300 (PseudoCAP)	OVER-SPECIFIC	Partial growth defect on His in a Biolog/plate screen; no uptake assay, no induction by His; MetI-family permease. Supports amino acid transport (the node term), not His as substrate.	E. coli MetI P31547 (IMP D-Met transport PMID:12218041; EXP methionine transport and ABC-type D-Met transporter activity PMID:12169620)	Yes

PSEUDOCAP defect: 1 SUSPECTED WRONG_TERM CHECK on GO:1903810. No GO_CENTRAL
defect. The node term itself is a sound generalization for the MetI clade.
PA5504 does not receive the GO:0006865 leaf IBA in GOA; it carries the more
specific GO:0048473 IBA from the child node PTN000765164 (MetI seed), accepted.
