Enzyme Information
| 1.4.3.16 |
L-aspartate oxidase.
based on mapping to UniProt Q8ZMX9
L-aspartate + O(2) = iminosuccinate + H(2)O(2).
-!- L-aspartate oxidase catalyzes the first step in the de novo biosynthesis of NAD(+) in some bacteria. -!- O(2) can be replaced by fumarate as electron acceptor, yielding succinate. -!- The ability of the enzyme to use both O(2) and fumarate in cofactor reoxidation enables it to function under both aerobic and anaerobic conditions. -!- Iminosuccinate can either be hydrolyzed to form oxaloacetate and NH(3) or can be used by EC 2.5.1.72 in the production of quinolinate.
