Pyroglutamic acid : throwing light on a lightly studied metabolite

  title={Pyroglutamic acid : throwing light on a lightly studied metabolite},
  author={Akhilesh Kumar and Anand Kumar Bachhawat},
Pyroglutamic acid or 5-oxoproline is the cyclic lactam of glutamic acid. Its presence in living cells has been reported from archaebacteria to humans, and its occurrence in living cells has been known for over a century. Despite its almost ubiquitous presence, the role of pyroglutamic acid in living cells is poorly understood. Pyroglutamic acid is found as an N-terminal modification in many neuronal peptides and hormones that also include the accumulating peptides in Alzheimer’s disease and…

Acetaminophen toxicity and 5-oxoproline (pyroglutamic acid): a tale of two cycles, one an ATP-depleting futile cycle and the other a useful cycle.

An ATP-depleting futile 5-Oxoproline cycle can explain the accumulation of 5-oxopro line after chronic acetaminophen ingestion and contributes to the understanding of acetaminphen-induced 5- oxoproine metabolic acidosis and the beneficial role of N-acetyl cysteine therapy.
Glutathione Degradation.
Glutathione degradation plays a far greater role in cellular physiology than previously envisaged and the differential regulation and differential specificities of various enzymes, each acting on distinct pools, can lead to different consequences to the cell.
Functional Characterization of 5-Oxoproline Transport via SLC16A1/MCT1*
It is concluded that H+-coupled 5-oxoproline transport is mediated solely by SLC16A1 in the cells, and Na+-dependent and amino acid transport systems scarcely contributed to 5-Oxopro line transport.
A Multi-Biochemical and In Silico Study on Anti-Enzymatic Actions of Pyroglutamic Acid against PDE-5, ACE, and Urease Using Various Analytical Techniques: Unexplored Pharmacological Properties and Cytotoxicity Evaluation
In the current study, pyroglutamic acid (pGlu), a natural amino acid derivative, has efficiently inhibited the catalytic activities of three important enzymes, namely: Human recombinant
Posttranslational Modifications and the Immunogenicity of Biotherapeutics
Whilst the amino acid sequence of a protein is determined by its gene sequence, the final structure and function are determined by posttranslational modifications (PTMs), including quality control
Susceptibility of protein therapeutics to spontaneous chemical modifications by oxidation, cyclization, and elimination reactions
This review focuses on protein chemical modifications that may take place during storage due to oxidation, intra- and inter-residue cyclization, and β-elimination and includes some examples of the impact of such modifications on protein structure and function.
The Impact of Pyroglutamate: Sulfolobus acidocaldarius Has a Growth Advantage over Saccharolobus solfataricus in Glutamate-Containing Media
Bioinformatical analyses showed that both members of the Sulfolobaceae have at least one candidate for a 5-oxoprolinase, which catalyses the ATP-dependent conversion of pyroglutamate to glutamate, making it a better candidate for applications with glutamate-containing media at high temperatures.
Role of Glycanation and Convertase Maturation of Soluble Glypican-3 in Inhibiting Proliferation of Hepatocellular Carcinoma Cells.
It is shown that glycanation and convertase maturation are not required for sGPC3m to inhibit HCC cell proliferation, and the levels of apoptosis, cell division, and β-catenin were not altered by the protein, although growth inhibition was very efficient.
Small molecule immunomodulins from cultures of the human microbiome member Lactobacillus plantarum
The metabolomic shifts revealed by principal component analysis that correspond to the mid-log-stationary transition of L. plantarum are presented, and pyroglutamic (pyro) dipeptides within this transition as correlative with the immunomodulatory actions are identified.
Computational Studies on the Mechanisms of Nonenzymatic Intramolecular Cyclization of the Glutamine Residues Located at N-Termini Catalyzed by Inorganic Phosphate Species
The computational results indicate that the flexibility of the main and side chains in N-terminal Gln residues was necessary for the formation of pGlu residues to proceed, and in the obtained pathway, inorganic phosphate species act as the catalyst by mediating the proton transfer.


Formation of pyroglutamic acid from N-terminal glutamic acid in immunoglobulin gamma antibodies.
To the knowledge, it is shown for the first time that glutamic acid residues located at the N-terminus of proteins undergo pyroglutamic acid formation in vitro.

It is suggested that the only major pathway by which pyroglutamate may be formed in epidermal tissue is from L-glutamate by a 2-step reaction, the first involving the formation of a gamma- glutamyl peptide by the action of gamma-glUTamyl-cysteine synthetase.
N-terminal Glutamate to Pyroglutamate Conversion in Vivo for Human IgG2 Antibodies
Investigation of to what extent human IgG2 N-terminal glutamate converts to pE in vivo found differences in the conversion rates between the light chain and heavy chain on an antibody were eliminated by denaturing the protein, revealing that structural elements affect pE formation rates.
Impaired activity of the gamma-glutamyl cycle in nephropathic cystinosis fibroblasts.
The hypothesis that cysteine derived from lysosomal cystine efflux limits the activity of the gamma-glutamyl cycle and GSH synthesis is supported.
5-Oxo-~-prolinase (L-Pyroglutamate Hydrolase)
It was shown that the enzyme also catalyzes the intrinsically exergonic hydrolysis of cr-hydroxyglutar- ate lactone, a reaction that is ATP-dependent, and the findings are consistent with a mechanism in which B-oxo-~-proline is phosphorylated by ATP on the amide carbonyl oxygen and the resulting intermediate is subsequently hydrolyzed to yield y-glutamyl phos- phate.
The identification and structural characterization of C7orf24 as gamma-glutamyl cyclotransferase. An essential enzyme in the gamma-glutamyl cycle.
A potential active site pocket that contains a highly conserved glutamic acid (Glu(98) to Ala or Gln completely inactivates the enzyme without altering the overall fold, and is proposed to refer to this structure as the gamma-glutamyl cyclotransferase fold.
