The citric acid or tricarboxylic acid cycle is a central element of higher-plant carbon metabolism which provides, among other things, electrons for oxidative phosphorylation in the inner mitochondrial membrane, intermediates for aminoacid biosynthesis, and oxaloacetate for gluconeogenesis from succinate derived from fatty acids via the glyoxylate cycle in glyoxysomes. The tricarboxylic acid cycle is a typical mitochondrial pathway and is widespread among a-proteobacteria, the group of eubacteria as de®ned under rRNA systematics from which mitochondria arose. ...

The enzyme a-amino-b-carboxymuconate-e-semialdehyde decarboxylase (ACMSD) is a zinc-dependent amidohydrolase that participates in picolinic acid (PA), quinolinic acid (QA) and NAD homeostasis. Indeed, the enzyme stands at a branch point of the tryptophan to NAD pathway, and deter-mines the final fate of the amino acid, i.e. transformation into PA, com-plete oxidation through the citric acid cycle, or conversion into NAD through QA synthesis.

Early metabolic steps, including glycolysis and the activity of the pyruvate dehydrogenase complex, yield a two-carbon fragment called an acetyl group, which is linked to a large cofactor known as coenzyme A (or CoA). It is during the citric acid cycle that acetyl-CoA is oxidized to the waste product, carbon dioxide, along with the reduction of the cofactors NAD+ and ubiquinone
