L-Cysteine Degradation

Escherichia coli
The degradation of cysteine starts with L-cysteine reacting with l-cysteine desulfhydrase resulting in the release of a hydrogen sulfide, a hydrogen ion and a a 2-aminoprop-2-enoate. The latter compound in turn reacts spontaneously to form a 2-iminopropanoate. This compound in turn reacts spontaneously with water and a hydrogen ion resulting in the release of ammonium and pyruvate.

L-Glutamate Metabolism

Shewanella denitrificans
There are various ways by which glutamate enters the cytoplasm in E.coli, such as through a glutamate:sodium symporter, glutamate / aspartate : H+ symporter GltP or a glutamate / aspartate ABC transporter. Similarly, there are various ways by which E. coli synthesizes glutamate from L-glutamine or oxoglutaric acid. L-glutamine, introduced into the cytoplasm by glutamine ABC transporter, can either interact with glutaminase resulting in ammonia and L-glutamic acid, or react with oxoglutaric acid, and hydrogen ion through an NADPH driven glutamate synthase resulting in L-glutamic acid. L-glutamic acid is metabolized into L-glutamine by reacting with ammonium through a ATP driven glutamine synthase. L-glutamic acid can also be metabolized into L-aspartic acid by reacting with oxalacetic acid through an aspartate transaminase resulting in an oxoglutaric acid and L-aspartic acid. L-aspartic acid is metabolized into fumaric acid through an aspartate ammonia-lyase. Fumaric acid can be introduced into the cytoplasm through 3 methods: dicarboxylate transporter, C4 dicarboxylate / C4 monocarboxylate transporter DauA, and C4 dicarboxylate / orotate:H+ symporter.

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.
