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-Galacturonate degradation

Escherichia coli str. K-12 substr. MG1655
D-Galacturonate degradation is a key metabolic pathway in bacteria that allows them to utilize D-galacturonate, a major component of pectin, as a carbon and energy source. D-Galacturonate is primarily derived from the degradation of plant biomass, particularly the breakdown of pectin, which is abundant in the cell walls of fruits and other plant tissues. Pectin is hydrolyzed by pectinolytic enzymes, releasing D-galacturonate monomers into the environment. Once transported into the bacterial cell, D-galacturonate is metabolized via a series of enzymatic reactions. It is first reduced to D-galactonate, which is then dehydrated to 2-keto-3-deoxy-galactonate (KDG). KDG is further cleaved into pyruvate and glyceraldehyde-3-phosphate, which can enter central metabolic pathways such as glycolysis and the tricarboxylic acid (TCA) cycle for energy production and biosynthesis. This degradation pathway is particularly important for soil bacteria and plant pathogens, enabling them to thrive in plant-rich environments by utilizing pectin-derived sugars. Additionally, D-galacturonate metabolism contributes to the global carbon cycle by recycling plant-derived carbohydrates.

D-Glucarate and D-Galactarate Degradation

Providencia rustigianii DSM 4541
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.
