Enables ATP citrate synthase activity. Predicted to be involved in acetyl-CoA biosynthetic process and carboxylic acid metabolic process. Predicted to act upstream of or within lipid metabolic process. Located in mitochondrion. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Orthologous to human ACLY (ATP citrate lyase).
