Q9VB17 is the 326-residue product of FBgn0039531. FlyBase identifies PA (AAF56726/NP_651574) and PC (AGB96396/NP_001263016) as identical products; both therefore correspond to this sequence. FlyBase, saved in CG5611-flybase.txt; exact frozen UniProt and ProtNLM records are preserved alongside the review.
The sequence record contains DR Pfam; PF00378; ECH_1; 1. and InterPro IPR001753/IPR029045. These establish the crotonase-like family, but not an exact substrate or pathway. No narrow subfamily or experimentally characterized ortholog establishes the proposed fatty-acid-oxidation role in the evidence assembled here. The three ND root annotations are retained; no positive catalytic core is invented.
The Falcon report completed in 412.51 seconds. Its literature synthesis identifies a behavioral screening lead (Walkinshaw et al., DOI 10.1534/genetics.114.173575), not a biochemical characterization. That lead is not promoted to a memory annotation because the screen and activity confound require further examination. Its general crotonase-family discussion is useful context, not independent evidence that this particular protein oxidizes fatty acids. The absence of a direct assay alone would not defeat a justified close-family transfer; the present missing element is a diagnostic subfamily/ortholog link establishing the reaction.
The original function text is copied from the probable enoyl-CoA hydratase Q52995 of Ensifer meliloti, with source similarity score 113.5; the donor's own sentence is tentative and similarity-derived. The mitochondrial location suggestion has a separate donor, mouse ECHDC2 Q3TLP5 (score 95.8). Neither raw similarity score specifies coverage or targeting-sequence conservation. These donors identify hypothesis provenance, not validation. The exact original sentence and its UNC assessment are in the accompanying function review.
Validation advisories about absent positive core or uncited provider text reflect the unresolved biological assignment and use of underlying sources. They do not indicate unreviewed GOA rows.
