Enables 3 iron, 4 sulfur cluster binding activity; 4 iron, 4 sulfur cluster binding activity; and aconitate hydratase activity. Involved in several processes, including response to isolation stress; tricarboxylic acid cycle; and tricarboxylic acid metabolic process. Located in mitochondrion. Human ortholog(s) of this gene implicated in infantile cerebellar-retinal degeneration and optic atrophy 9. Orthologous to human ACO2 (aconitase 2).
