There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
L-aspartate oxidase. [EC: 1.4.3.16]
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.
