Enables acetyl-CoA C-acyltransferase activity; acetyl-CoA C-myristoyltransferase activity; and palmitoyl-CoA oxidase activity. Involved in several processes, including monocarboxylic acid metabolic process; response to nutrient; and response to steroid hormone. Located in peroxisome. Orthologous to human ACAA1 (acetyl-CoA acyltransferase 1). [provided by Alliance of Genome Resources, Apr 2022]
