aceE

Gene Description

aceE (PP_0339) encodes the E1 component of pyruvate dehydrogenase, a thiamine-diphosphate enzyme that decarboxylates pyruvate and transfers the resulting hydroxyethyl/acetyl equivalent to the lipoyl group of the E2 component. Together with AceF and lipoamide dehydrogenase, it supports oxidative decarboxylation of pyruvate to acetyl-CoA in central carbon metabolism.

Existing Annotations Review

GO Term	Evidence	Action	Reason
GO:0004739 pyruvate dehydrogenase (acetyl-transferring) activity	IEA GO_REF:0000120	ACCEPT	Summary: pyruvate dehydrogenase (acetyl-transferring) activity is consistent with the curated UniProt name, EC/family evidence, and the gene product role summarized here. Reason: This is a specific, biologically appropriate annotation for this gene product.
GO:0016491 oxidoreductase activity	IEA GO_REF:0000002	KEEP AS NON CORE	Summary: oxidoreductase activity is biologically plausible for this enzyme but is ancillary to the more specific catalytic function. Reason: Retain as a supporting/non-core annotation rather than using it as the main functional summary.
