Species: Gossypium hirsutum
L-aspartate oxidase was partially purified from callus tissues of Gossypium hirsutum. The enzyme expressed high specificity towards L-aspartate and did not accept L-glutamate, D-aspartate or D- or L-alanine [Hosokawa83].
Molecular Weight of Polypeptide: 83 kD (experimental) [Hosokawa83 ]
EC Number: 188.8.131.52
