GO Classification

Functions

acyl-CoA dehydrogenase activity / electron carrier activity / fatty-acyl-CoA binding / flavin adenine dinucleotide binding / oxidoreductase activity, acting on the CH-CH group of donors, with a flavin as acceptor

Processes

branched-chain amino acid catabolic process / cellular nitrogen compound metabolic process / fatty acid beta-oxidation using acyl-CoA dehydrogenase / fatty acid metabolic process / lipid homeostasis / small molecule metabolic process

Components

extracellular exosome / mitochondrial matrix / mitochondrion

General Function

Oxidoreductase activity, acting on the ch-ch group of donors, with a flavin as acceptor

Specific Function

Has greatest activity toward short branched chain acyl-CoA derivative such as (s)-2-methylbutyryl-CoA, isobutyryl-CoA, and 2-methylhexanoyl-CoA as well as toward short straight chain acyl-CoAs such as butyryl-CoA and hexanoyl-CoA. Can use valproyl-CoA as substrate and may play a role in controlling the metabolic flux of valproic acid in the development of toxicity of this agent.

Pfam Domain Function

• Acyl-CoA_dh_1 (PF00441)
• Acyl-CoA_dh_M (PF02770)
• Acyl-CoA_dh_N (PF02771)
