A flavoprotein (FAD); forms with another flavoprotein ('electron-transferring flavoprotein') and EC a system reducing ubiquinone and other acceptors. Not identical with EC (butyryl-CoA dehydrogenase), EC (acyl-CoA dehydrogenase), EC (isovaleryl-CoA dehydrogenase) or EC (2-methylacyl-CoA dehydrogenase).

Rate-limiting Description

"Although the rate-limiting step in the inactivation of the other acyl-CoA dehydrogenases can involve the abstraction of a proton at C-4, this is not the case with glutaryl-CoA dehydrogenase." (12716879)

Regulatory Information

Upstream transcription factor


Regulatory type

key enzyme;

"Very long-chain acyl-CoA dehydrogenase deficiency (VLCAD) is a key enzyme catalysing the dehydrogenation of long-chain fatty acids in mitochondrial beta-oxidation." (16880373#10832093)

transcriptional factor;

"We conclude that the developmental and tissue-specific regulation of the human LCAD gene is mediated, in part, by these nuclear hormone receptor transcription factors." (9003458)

Disease relevance


Defects in ACADL are the cause of long-chain acyl-CoA dehydrogenase deficiency (LCAD deficiency) [MIM:201460]. LCAD deficiency leads to non-ketotic hypoglycemia [P28330 ];
