PP_3768

Existing Annotations Review

GO Term	Evidence	Action	Reason
GO:0004764 shikimate 3-dehydrogenase (NADP+) activity	IEA GO_REF:0000120	ACCEPT	Summary: PP_3768 has shikimate-dehydrogenase family/domain evidence and GOA maps it to NADP-dependent shikimate dehydrogenase activity, but the UniProt description remains a submitted shikimate 5-dehydrogenase/EC 1.1.1.- annotation. Reason: The molecular function is plausible and supported by InterPro/PANTHER/TreeGrafter-style evidence, but it should be treated as inferred rather than directly characterized. No stronger alternate GO MF term is currently available from the supplied evidence.
GO:0005829 cytosol	IEA GO_REF:0000118	ACCEPT	Summary: Predicted cytosolic localization for a soluble shikimate-dehydrogenase-like enzyme. Reason: The protein lacks membrane or secretion features and belongs to a soluble metabolic enzyme family.
GO:0009423 chorismate biosynthetic process	IEA GO_REF:0000118	ACCEPT	Summary: The annotation places this aroE-like protein in the shikimate/chorismate pathway. Reason: This is reasonable pathway context for a shikimate-dehydrogenase-like protein. PP_3768 remains a weak module-satisfying candidate because KT2440 has several more canonical aroE paralogs and this entry lacks direct biochemical or genetic evidence, but the chorismate-pathway annotation itself is appropriate.
GO:0016491 oxidoreductase activity	IEA GO_REF:0000117	MARK AS OVER ANNOTATED	Summary: Broad oxidoreductase parent term for the predicted shikimate dehydrogenase-like activity. Reason: The specific shikimate dehydrogenase activity annotation is more informative; the generic oxidoreductase parent adds little.
GO:0019632 shikimate metabolic process	IEA GO_REF:0000118	KEEP AS NON CORE	Summary: Correct broad pathway context for an aroE-like enzyme, but not enough to establish this paralog as a core shikimate-pathway copy. Reason: Retain as broader process context while noting that PP_3768's precise physiological role remains unresolved.
GO:0050661 NADP binding	IEA GO_REF:0000118	ACCEPT	Summary: NADP binding is consistent with the NAD(P)-binding oxidoreductase fold and the shikimate dehydrogenase family assignment. Reason: Cofactor-binding inference is supported by conserved domain architecture and is integral to the predicted oxidoreductase activity.
