We are deeply saddened by the passing of Amos Bairoch (1957–2025), the creator of PROSITE. We wish to dedicate our latest paper, published shortly before his death, to him. He will always be a source of inspiration to us.
Our deepest condolences go out to his family and friends, and to all those who had the privilege of working with him. Rest in peace, Amos. Your work will live on long after you are gone.

Description
Acyl-CoA dehydrogenases [1,2,3] are enzymes that catalyze the α,β-dehydrogenation of acyl-CoA esters and transfer electrons to ETF, the electron transfer protein. Acyl-CoA dehydrogenases are FAD flavoproteins. This family currently includes:
- Five eukaryotic isozymes that catalyze the first step of the β-oxidation cycles for fatty acids with various chain lengths. These are short (SCAD) (EC 1.3.99.2), medium (MCAD) (EC 1.3.99.3), long (LCAD) (EC 1.3.99.13), very-long (VLCAD) and short/branched (SBCAD) chain acyl-CoA dehydrogenases. These enzymes are located in the mitochondrion. They are all homotetrameric proteins of about 400 amino acid residues except VLCAD which is a dimer and which contains, in its mature form, about 600 residues.
- Glutaryl-CoA dehydrogenase (EC 1.3.99.7) (GCDH), which is involved in the catabolism of lysine, hydroxylysine and tryptophan.
- Isovaleryl-CoA dehydrogenase (EC 1.3.99.10) (IVD), involved in the catabolism of leucine.
- Acyl-coA dehydrogenases acdA and mmgC from Bacillus subtilis.
- Butyryl-CoA dehydrogenase (EC 1.3.99.2) from Clostridium acetobutylicum.
- Escherichia coli protein caiA [4].
- Escherichia coli protein aidB.
We have selected two conserved regions as signature patterns. The first is located in the center of these enzymes, the second in the C-terminal section.
