Asparagine Biosynthesis

Pseudomonas aeruginosa
Asparagine is an amino acid used in protein synthesis, specifically the biosynthesis of glycoproteins. In E.coli, L-asparagine can be synthesized from L-aspartic acid by either utilizing asparagine synthetase B with L-glutamine or ammonia. Both reactions are driven by ATP however the reaction with ammonia utilizes both asparagine synthetase B and aspartate-ammonia ligase.

Asparagine Metabolism

Saccharomyces cerevisiae
In both eukaryotes and prokaryotes, L-asparagine is biosynthesized from L-aspartate by amidation using L-glutamine as an amino group donor which both of reactions are driven by ATP. In the first reaction, asparagine synthetase [glutamine-hydrolyzing] 1 catalyzes L-aspartic acid to form L-Asparagine. In the second reactions, asparagine synthetase [glutamine-hydrolyzing] 1 and 2 both catalyze L-aspartic acid to form L-Asparagine. Asparagine gets metabolized back into L-aspartic acid by reacting with water through a L-asparaginase 1 resulting in the release of ammonium and L-aspartic acid. The only known role of L-asparagine is incorporation into proteins.

Asparagine Metabolism

Arabidopsis thaliana
Asparagine is one of the twenty amino acids that combine to construct proteins according to the genetic code. In both eukaryotes and prokaryotes, L-asparagine is biosynthesized from L-aspartate via amidation using L-glutamine as an amino group donor. The first of the two reactions involved is catalyzed by asparagine synthetase [glutamine-hydrolyzing] 1. However, the second reaction is catalyzed by both asparagine synthetase [glutamine-hydrolyzing] 1 and 2. Asparagine synthetase 1 is negatively controlled by light and sucrose whereas asparagine synthetase 2 is positively controlled by light and sucrose. Asparagine gets metabolized back into L-aspartic acid by reacting with water through an L-asparaginase, resulting in the release of ammonium and L-aspartic acid.

Aspartate Metabolism

Drosophila melanogaster
Aspartate is synthesized by transamination of oxaloacetate by aspartate aminotransferase or amino acid oxidase. Aspartyl-tRNA synthetase can then couple aspartate to aspartyl tRNA for protein synthesis. The aspartate content in human proteins is about 7%. Asparagine synthase can convert aspartate to the polar amino acid asparagine. Aspartate is also a precursor for cellular signaling compounds such as, N-acetyl-aspartate, beta-alanine, adenylsuccinate, arginino-succinate and N-carbamoylaspartate. Aspartate is also a metabolite in the urea cycle and involved in gluconeogenesis. Additionally, aspartate carries the reducing equivalents in the mitochondrial malate-aspartate shuttle, which utilizes the ready interconversion of aspartate and oxaloacetate. The conjugate base of L-aspartic acid, aspartate, also acts as an excitatory neurotransmitter in the brain which activates NMDA receptors.

Aspartate Metabolism

Escherichia coli
Aspartate is synthesized from and broken down to oxaloacetate, a TCA cycle intermediate, via a reversible transamination reaction with glutamate. This reaction is catalyzed by the aminotransferase AspC or TyrB. Aspartate is a component of proteins and is involved in many biosyntheses pathways like NAD biosynthesis and beta-alanine metabolism. Aspartate can also be synthesized from fumaric acid through an aspartate ammonia lyase. Aspartate also participates in the synthesis of L-asparagine through two different methods, either through aspartate ammonia ligase or asparagine synthetase B. Aspartate is also a precursor of fumaric acid. Again it has two possible ways of synthesizing it. First set of reactions follows an adenylo succinate synthetase that yields adenylsuccinic acid and then adenylosuccinate lyase in turns leads to fumaric acid. The second way is through argininosuccinate synthase that yields argininosuccinic acid and then argininosuccinate lyase in turns leads to fumaric acid.
