D-aminokiselina transaminaza (EC 2.6.1.21, D-aspartatna transaminaza, D-alaninska aminotransferaza, D-aspartinska aminotransferaza, D-alanin-D-glutamatna transaminaza, D-alaninska transaminaza, D-aminokiselinska aminotransferaza) je enzim sa sistematskim imenom D-alanin:2-oksoglutarat aminotransferaza.[1][2][3][4][5][6][7][8][9] Ovaj enzim katalizuje sledeću hemijsku reakciju
- D-alanin + 2-oksoglutarat piruvat + D-glutamat
Ovaj enzim je piridoksal-fosfatni protein. Enzim iz termofilnih Bacillus vrsta deluje na mnoge D-aminokiseline. D-alanin i D-2-aminobutirat su najbolji amino donori.
