The L-aspartate oxidase reported to be present in higher plants is actually glutamic oxaloacetic transaminase

We previously reported (Biochem. Biophys. Res. Commun. (1983) 111, 188-193) that cotton callus cells contain an L-aspartate oxidase which requires an unidentified cofactor with an apparent molecular weight of 1,050. Further study has revealed that this report was in error. The enzyme is actually glutamic oxaloacetic transaminase and the "cofactor" has been identified as alpha-ketoglutarate.
