FunFam 5: Quinolinate synthase A

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
Quinolinate synthase. [EC: 2.5.1.72]
Glycerone phosphate + iminosuccinate = pyridine-2,3-dicarboxylate + 2 H(2)O + phosphate.
  • Quinolinate synthase catalyzes the second step in the de novo biosynthesis of NAD(+) from aspartate in some bacteria, with EC 1.4.3.16 catalyzing the first step and EC 2.4.2.19 the third step.
  • In Escherichia coli, two of the residues that are involved in the [4Fe-4S] cluster binding appear to undergo reversible disulfide-bond formation that regulates the activity of the enzyme.
