Mitochondrial ornithine aminotransferase (OAT) catalyzes the reversible reaction of ornithine and alpha-ketoglutarate to form glutamate semialdehyde and glutamate (Ohura et al. 1982). The active enzyme is a hexamer (Shen et al. 1998). Inherited OAT deficiency leads to ornithine accumulation in vivo and gyrate atrophy of the choroid and retina (Brody et al. 1992; Valle and Simell 2001).
