Existing Annotations Review

GO Term	Evidence	Action	Reason
GO:0005315 phosphate transmembrane transporter activity	IEA GO_REF:0000002	MODIFY	Summary: The function is correct at the assembled-permease level, but PstA is one subunit of the PstA/PstC membrane pair and does not independently enable it. Reason: Retain GO:0005315 with contributes_to rather than enables. Proposed replacements: phosphate transmembrane transporter activity Supporting Evidence: file:PSEPK/pstA/pstA-uniprot.txt RecName: Full=Phosphate transport system permease protein PstA
GO:0005886 plasma membrane	IEA GO_REF:0000120	ACCEPT	Summary: Correct specific membrane location for this multipass permease subunit.
GO:0016020 membrane	IEA GO_REF:0000120	KEEP AS NON CORE	Summary: Correct but less precise than the plasma-membrane annotation.
GO:0035435 phosphate ion transmembrane transport	IEA GO_REF:0000002	ACCEPT	Summary: Directly captures the phosphate-uptake process performed by the Pst complex.
GO:0043190 ATP-binding cassette (ABC) transporter complex	IEA GO_REF:0000104	MODIFY	Summary: PstA is a membrane component of a substrate-binding-subunit-containing PstSACB transporter. Reason: Use the specific ABC importer complex term that explicitly includes a substrate-binding subunit. Proposed replacements: ATP-binding cassette (ABC) transporter complex, substrate-binding subunit-containing
GO:0055085 transmembrane transport	IEA GO_REF:0000002	MARK AS OVER ANNOTATED	Summary: Directionally correct but unnecessarily broad relative to phosphate ion transmembrane transport. Reason: The phosphate-specific process is already present as a separate annotation, making this generic parent redundant.
