Mitochondrial HOGA1 aldol-cleaves 4-OH-2-oxoglutarate (HOG) to glyoxylate and pyruvate. The biochemical details of the enzyme are inferred from the properties of its well-studied rat homologue (Maitra & Dekker 1964). The mature protein lacks a 25-residue mitochondrial targeting sequence and forms a homotetramer (Riedel et al. 2011).
