EC - Alanopine dehydrogenase

  IntEnz view ENZYME view

IntEnz Enzyme Nomenclature


Accepted name:
alanopine dehydrogenase
Other names:
meso-N-(1-carboxyethyl)-alanine:NAD+ oxidoreductase
alanopine: NAD oxidoreductase
alanopine:NAD oxidoreductase
Systematic name:
2,2'-iminodipropanoate:NAD+ oxidoreductase (L-alanine-forming)



In the reverse reaction, L-alanine can be replaced by L-cysteine, L-serine or L-threonine; glycine acts very slowly (cf. EC strombine dehydrogenase).
