Amino Acid Sequence

Gly-Gly-Gly

General description

Gly-Gly-Gly or triglycine is a flexible peptide linker with three glycine residues linked by peptide bonds in a linear sequence. Gly-linkers link multiple domains in a single protein without affecting the function of each domain.

Application

<ul>
<li><strong>Targeting PEPT1: a novel strategy to improve the antitumor efficacy of doxorubicin in human hepatocellular carcinoma therapy:</strong> Research explores Gly-Gly-Gly peptides as potential enhancers for drug transport efficiency, positioning them as valuable tools in clinical diagnostic peptide development for targeted cancer therapies (Gong et al., 2017).</li>
<li><strong>Iminopyridine complexes of manganese, rhenium, and molybdenum derived from amino ester methylserine and peptides Gly-Gly, Gly-Val, and Gly-Gly-Gly: self-assembly of the peptide chains:</strong> This study demonstrates the use of Gly-Gly-Gly in the synthesis of complex metal-peptide frameworks for potential use in high-purity peptide applications in IVD manufacturing (&Aacute;lvarez et al., 2012).</li>

Linkers or spacers are short amino acid sequences created in nature to separate multiple domains in a single protein. Most of them are rigid and function to prohibit unwanted interactions between the discrete domains. However, Gly-rich linkers are flexible, connecting

Fragmentations of tautomers of the alpha-centered radical triglycine radical cation, [GGG(*)](+), [GG(*)G](+), and [G(*)GG](+), are charge-driven, giving b-type ions; these are processes that are facilitated by a mobile proton, as in the fragmentation of protonated triglycine (Rodriquez, C. F. et

Nitrogen K-edge spectra of aqueous triglycine were measured using liquid microjets, and the effects of Hofmeister-active salts on the spectra were observed. Spectra simulated using density functional theory, sampled from room temperature classical molecular dynamics trajectories, capture all major features
