Application

Serine has been used as an inhibitor of seryl-tRNA synthetase. DL-Serine hydroxamate is used to induce metabolic synthesis of guanosine 3′-diphosphate 5′-diphosphate (ppGpp) in E. coli by amino acid starvation. It is also used to synchronize cell cycle in E. coli cultures by inhibition of tRNA charging.

Biochem/physiol Actions

Serine is involved in the one-carbon unit metabolism. It is associated with the biosynthesis of cysteine, ceramide, phosphatidylserine, purine and pyrimidine. In bacteria, it participates in tryptophan synthesis. Gluconeogenesis, one of the important biochemical processes, involves serine, particularly in ruminants. Protein phosphorylation is one such event that utilizes serine. Glycine, a metabolic product of serine, serves as an antioxidant and a neurotransmitter. D-serine is known to activate the N-methyl-D-aspartate (NMDA) receptors of the brain. Serine hydroxamate, a structural analogue of serine prevents seryl-tRNA (transfer ribonucleic acid) charging and thereby decreases phospholipid and nucleic acid synthesis in Escherichia coli.

The stringent response is the initial reaction of microorganisms to nutritional stress. During stringent response the small nucleotides (p)ppGpp act as global regulators and reprogram bacterial transcription. In this work, the genetic network controlled by the stringent response was characterized

Bacteria become highly tolerant to antibiotics when nutrients are limited. The inactivity of antibiotic targets caused by starvation-induced growth arrest is thought to be a key mechanism producing tolerance. Here we show that the antibiotic tolerance of nutrient-limited and biofilm
