| Application: | Polyglycine has been used as an external intensity standard for measuring cross polarization (CP) nuclear magnetic resonance (NMR) spectrum measurements and ion mobility mass spectrometry. It is suitable for use as a model for UV resonance Raman spectroscopy studies. |
| Biochem/physiol Actions: | Polyglycine exists in two forms, namely the polyglycine I (PGI) with anti-parallel β-sheet structure and polyglycine II (PGII) with extended 31-helix. It is a most flexible polypeptide with minimal steric hindrance and its solubility increases in the presence of lithium ions. It is present in mammals and plants. Polyglycine stretch associated with the chloroplast membrane protein, Toc5 is essential for envelop sorting. |
