D-Arginine and D-Ornithine Metabolism

Drosophila melanogaster
D-Amino acids have been show to be present in high concentrations in humans and play a role in biological functions. D-Amino may have negative effects as they can be found in some bacteria or form spontaneously in certain reactions. D-Amino acid oxidase (DAAO) is one of the main enzymes that metabolize D-Amino acids via deamination. DAAO is highly specific towards D-amino acids and favours free neutral D-amino acids or those with hydrophobic, polar or aromatic groups. Acidic amino acids are not catalyze by DAOO.

D-Galactose Degradation (Leloir pathway)

Arabidopsis thaliana
The Leloir pathway is a metabolic pathway for the catabolism of D-galactose into D-glucopyranose 6-phosphate named after Luis Federico Leloir . Since galactose cannot be directly used for glycolysis, it needs to be converted into a different form. This pathway starts in the cytosol and finishes in the chloroplast. First, aldose 1-epimerase is a predicted enzyme (coloured orange in the image) that is theorized to catalyze the conversion of beta-D-galactose into alpha-D-galactose. This enzyme has not yet been elucidated for Arabidopsis thaliana. Second, galactokinase catalyzes the conversion of alpha-D-galactose into alpha-D-galactose 1-phosphate. Third, D-galactose-1-phosphate uridylyltransferase is a predicted enzyme theorized to catalyze the reaction whereby alpha-D-galactose 1-phosphate and UDP-glucose is converted into alpha-D-glucopyranose 1-phosphate and UDP-galactose. This enzyme has not yet been elucidated in Arabidopsis thaliana. UDP-glucose and UDP-galactose can be interconverted by the enzyme UDP-glucose 4-epimerase which requires NAD as a cofactor. Alpha-D-glucopyranose 1-phosphate must then be imported into the chloroplast, by a yet not discovered alpha-D-glucopyranose 1-phosphate transporter. Last, phosphoglucomutase uses magnesium ion as a cofactor to convert alpha-D-glucopyranose 1-phosphate into D-glucopyranose 6-phosphate.

D-Glucarate and D-Galactarate Degradation

Pseudomonas aeruginosa
Galactarate is a naturally occurring dicarboxylic acid analog of D-galactose. E. coli can use both diacid sugars galactarate and D-glucarate as the sole source of carbon for growth. The initial step in the degradation of galactarate is its dehydration to 5-dehydro-4-deoxy-D-glucarate(2--) by galactarate dehydratase. Glucaric acid can also be dehydrated by a glucarate dehydratase resulting in water and 5-dehydro-4-deoxy-D-glucarate(2--). The 5-dehydro-4-deoxy-D-glucarate(2--) is then metabolized by a alpha-dehydro-beta-deoxy-D-glucarate aldolase resulting in pyruvic acid and a tartonate semialdehyde. Pyruvic acid interacts with coenzyme A through a NAD driven Pyruvate dehydrogenase complex resulting in a carbon dioxide, an NADH and an acetyl-CoA. The tartronate semialdehyde interacts with a hydrogen ion through a NADPH driven tartronate semialdehyde reductase resulting in a NADP and a glyceric acid. The glyceric acid is phosphorylated by an ATP-driven glycerate kinase 2 resulting in an ADP, a hydrogen ion and a 2-phosphoglyceric acid. The latter compound is dehydrated by an enolase resulting in the release of water and a phosphoenolpyruvic acid. The phosphoenolpyruvic acid interacts with a hydrogen ion through an ADP driven pyruvate kinase resulting in an ATP and a pyruvic acid. The pyruvic acid then interacts with water and an ATP through a phosphoenolpyruvate synthetase resulting in the release of a hydrogen ion, a phosphate, an AMP and a Phosphoenolpyruvic acid.
