Biology

Last gene of the carnitine operon; not needed for carnitine catabolism PMID:23524670.
Short-chain acylcarnitine hydrolase PMID:23524670.
Family: GDXG lipolytic enzyme / AB_hydrolase_3 (PF07859); unreviewed UniProt entry (PE 3).
Operon regulator: CdhR (PA5389), reviewed in genes/PSEAE/cdhR.
No GO term for acylcarnitine catabolism; carnitine catabolism terms would be wrong (PA5384 acts
upstream of carnitine).

GO:0047619 (IDA, PseudoCAP): ACCEPT, core MF.
GO:0034338 (IBA, PTN000546472): ACCEPT (reaction falls within the definition; not is_a related).
GO:0016787 (IEA): TOO_GENERAL.
Action counts: ACCEPT 2, TOO_GENERAL 1.

No GO_CENTRAL or PSEUDOCAP defect. PA5384's own IBA comes from the descendant node PTN000546472
(GO:0034338), which PA5384 does not seed.
