L-Homomethionine Biosynthesis

Arabidopsis thaliana
A non-protein amino acid and a derivative of methionine, homomethionine is synthesized through the process of chain elongation. In Arabidopsis thaliana and other members of the Cruciferae (Brassicaceae) family, it is synthesized as part of a multi-step pathway to generate glucosinolates. Glucosinolates are likely employed as a defense mechanism and are believed to be responsible for the pungent odour and taste associated with this plant family. The process starts in the cytosol of the plant cell with l-methionine as the primary substrate before moving into the chloroplast as 2-oxo-4-methylthiobutanoic acid. In the chloroplast, 3-isopropylmalate dehydratase plays a noteworthy role in catalyzing multiple reactions in the final synthesis of L-homomethionine.

L-Lactaldehyde Degradation (Aerobic)

Pseudomonas aeruginosa
(S)-lactaldehyde is derived from degradation of L-fucose and rhamnose. (S)-lactaldehyde is converted to lactic acid by lactaldehyde dehydrogenase with NAD as cofactor. L-lactate dehydrogenase dehydrogenates lactic acid to pyruvic acid for the pathway of glycolysis and pyruvate dehydrogenase.

L-Leucine degradation

Streptomyces avermitilis
Leucine degradation is a key metabolic process that converts the essential amino acid leucine into energy and intermediate molecules used in various biosynthetic pathways.This pathway includes several enzymatic steps that ultimately transform leucine into acetyl-CoA and acetoacetate, both of which are crucial for the tricarboxylic acid (TCA) cycle and fatty acid synthesis. These reactions not only contribute to the organism's energy production but also provide necessary building blocks for the synthesis of vital compounds.

L-Lyxose Degradation

Escherichia coli
L-lyxose is a sugar and a monosaccharide containing five carbon atoms and aldehyde group. Wild-type E.coli can't utilize L-lyxose as its source of carbon and energy. In mutated E.coli, it can metabolize l-lyxose through utilization of enzymes of the rhamnose, arabinose and 2,3-diketo-L-gulonate systems. β-L-lyxopyranose enter cell by L-rhamnose-proton symporter, then convert to l-xylulose by L-rhamnose isomerase. L-xylulose is further metabolized to L-xylulose-5-phosphate with energy ATP. Putative L-ribulose-5-phosphate 3-epimerase can convert L-xylulose -5-phosphate to L-ribulose 5-phosphate, and L-ribulose 5-phosphate 4-epimerase can catalyze L-ribulose 5-phosphate to xylulose 5-phosphate for further pentose phosphate.

L-Threonine Degradation to Methylglyoxal

Escherichia coli
L-threonine is degrade into methylglyoxal (pyruvaldehyde) by first reacting with a NDA dependent threonine dehydrogenase resulting in the release of a hydrogen ion, an NADH and a 2-amino-3-oxobutanoate. The latter compound reacts spontaneously with a hydrogen ion resulting in the release of a carbon dioxide and a aminoacetone. The aminoacetone in turn reacts with an oxygen and a water molecule through an aminoacetone oxidase resulting in the release of a hydrogen peroxide, ammonium and a methylglyoxal which can then be incorporated in the methylglyoxal degradation pathways.
