AAT-1 was purified 228,AAT-2,42 and AAT-3, 3.8 fold. The isoenzymes were examined by means ofpolyacrylamide gel electrophoresis.Owing to its key role in general metabolism, aspartate adotransferase (AAT, E.C. 2.6.1.1.) which was formerly called glutamic oxaloacetic transaminase (GOT), occurs widely in nature. In animals, cytbsolic and rnitochon+al forms of AAT have been characterized and purified (1-4). AAT has also been studied in various plants (5, 6) and different isoeozyrnic forms have been r&-, ported. The enzyme has been extensively characterized in wheat germ (7,8), cauliflower (9), cotton seeds (lo), pea (ll), soybean (12-14), oat (15), lupine (16) and alfalfa (17,18).
