ornithine delta-aminotransferase

or·ni·thine δ-·a·mi·no·trans·fer·ase

an enzyme that will reversibly catalyze the reaction of α-ketoglutarate and l-ornithine to form l-glutamate and l-glutamate γ-semialdehyde; a deficiency of this enzyme will result in gyrate atrophy of the choroid and retina. Synonym(s): ornithine transaminase
