3-Ketoacyl-CoA thiolase, peroxisomal also known as acetyl-Coenzyme A acyltransferase 1 is an enzyme that in humans is encoded by the ACAA1 gene.[1][2][3]

Acetyl-Coenzyme A acyltransferase 1 is an acetyl-CoA C-acyltransferase enzyme.


This gene encodes an enzyme operative in the beta oxidation system of the peroxisomes.[1]

Clinical significance[edit]

Deficiency of this enzyme leads to pseudo-Zellweger syndrome.[1]
