The Denaturation of α, β and Ψ Bovine Trypsin at Ph 3.0: Evidence of Intermediates
The conformational stability and the folding process of α, β and Ψ bovine trypsin at pH 3.0 followed by circular dichroism (CD) and size exclusion in HPLC have been analyzed as a function of urea concentration. The thermodynamic stability for α and β are ΔG = 15.91 ± 0.28 kcal / mol, DG = 15.54 ± 2.39 kcal / mol. respectively, and Ψ trypsin is ΔG = 16.10 ± 2.51 kcal / mol. The transition curves for α, β and Ψforms suggest a molten globule state.

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.
