Circular Dichroism Reveals Sensitivity of Glucagon Solution Structure to Fluoroalcohols, pH and Ionic Strength
Circular dichroism reports that glucagon in solution becomes increasingly helical with the addition of fluoroalcohol (which also decreases solution pH), and with changes in pH and ionic strength. Given the variability of structure observed, these data indicate that care must be taken when comparing results obtained under different solution conditions.

More about this publication?
- Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
